Keeper of the Light is a massive ♥♥♥♥♥♥ of a hero whose job it is to eliminate fun. Being a support hero, he requires no items whatsoever to kill you to death over and over again without remorse or pity and he possesses the power of Illuminate, which he can use to farm any item he could ever want. Unless you get one of those Russian KOTLs who max Illuminate first and steal every last hit possible, you will be glad to know that a KOTL on your team ensures that you have all the fun and the enemy has none whatsoever.

KOTL goes well with any team unless the enemy team has nyxnyxnyxnyxnyx or you have no stuns or crowd control of any description. This guide assumes you have a basic understanding of game mechanics and terminology.

Illuminate
Referred to the wave of death here on after, this is KOTL's primary way of being an ♥♥♥♥♥♥♥. It fires a massive wave of death in the direction you clicked on, doing lods of edamage and pissing off everyone who isn't you. The damage is based upon how long you channel the spell, with every 1 second equating to 100 damage, resulting in a maximum 200/300/400/500 damage.

FOR THE LOVE OF GOD, DO NOT JUST SIT THERE IN LANE AND SPAM IT, ESPECIALLY WHEN LANING WITH SOMEONE LIKE VOID OR PA. NOT ONLY WILL YOU HAVE NO MANAS IN THE EVENT OF AN EMERGENCY, BUT YOU WILL ALSO DEPRIVE YOUR LANEMATE OF FARM, BECAUSE IT'S A BIT DIFFICULT TO LAST HIT WHEN THE CREEPS ARE BEING SUBJECTED TO SEVEN THOUSAND HIROSHIMAS EVERY 10 SECONDS.

Mana Leak
This is basically Buttseeker's Ult except it drains Manas. For the uninformed, this spell results in enemy heroes losing mana as they move. This massively ♥♥♥♥♥ over people who rely upon going fast, like Weaver and Night Stalker, and also people with low mana pools. Do not underestimate the power of this skill! The stun is not terrible, but it relies upon people losing all their respective manas. It is better to cast this on dumb strength heroes rather than smart intelligence heroes.

Chakra Magic
A single target spell that gives people Mana. You can cast it on yourself, but you get less Mana from it as the cost for using this spell is taken into account. This spell is brilliant if you're laning with someone with a nasty stun/nuke but with low intelligence like Sven, so you can give him all the mana he needs to spam it. Many manas to give to hardworking proletariat class to make powerful strong glory team!

KOTTOL

GIFF ME CHAGRA MAGIC

Spirit Form
GLORIOUSH INCANDESHENSH

This is your ult, and it's why you have six skills. Using the Ult gives you access to two additional abilities (Blinding Light and Recall) and whenever you fire a wave of death at people a seperate spirit channels it so you don't have to sit there like a ♥♥♥♥ channeling yourself. Blinding Light produces a flash of light that knocks enemies back and makes them miss their attacks for a few seconds. Obviously use this in a teamfight or to save someone's skin if they're being chased, as the knockback could make the difference between life and death. Try not to knock people out of the way of unreliable stuns like Leshrac's or Mirana's, lest you experience an angry outburst of cyrillic characters. Recall is a bit like Chen's Test of Faith, except it isn't because it teleports people to you instead of the fountain and it is disabled if they take damage.

IT BEGINS
So you spawn in the fountain with 4 carries and already the cyrillic text flows. Don't poo yourself just yet, and buy any combination of these items from the suspiciously big-nosed shopkeeper:


Animal Courier and/or Wards are a given, because you are a strong white support who don't need no farm, and some regen items like tangoes and salves are also necessary. Clarities are unecessary for obvious reasons, and you should probably buy a gauntlet or circlet to make into a bracer at some point because you are a squishy pile of ♥♥♥♥ thanks to the IceFrog School of Hero Balance. If you have leftover monies/space fill the rest of your inventory with branches.

LANING
Try and lane with someone with a ranged spammble nuke/stun. Prime candidates include Phantom Lancer's Spirit Lance, DK's Fire Breath and Sven's Storm Bolt among others. The idea in doing this is to either kill them or scare them away from creep line, so your lane partner has free access to last hits. Take Chakra Magic first, as you will have more manas to give to your friend as well as give to yourself when firing off waves of death.

When charging waves of death, hide in the trees and aim the wave of death so that it does not hit the creeps, or hits as little of the creeps as possible. If you end up winning the lane hard and the enemy are too scared to even come into vision, you can leave your lane partner to farm while you can go off into the jungle to stack and pull camps and and farm them with wave of death. Don't suffer from tunnel vision and make sure to return if your friend needs help.

HURR DURR HOW DO I BUILD GANDALF
♥♥♥♥ depends. If you're laning against people who spam their abilities every 5 seconds like Buttrider and Lich, it would probably be smart to build a wand first. Otherwise, start building for a Mekansm (or drums if someone else is going to get Mek.) Get standard boots/flying courier/wards/whatever as necessary.

Skillwise, prioritise chakra over illuminate and ensure you have at least one point in Mana Leak before level 6.

OH MY GOD JC A TEAMFIGHT

This is the part that requires you to utilitize the power of 6 buttons to press without ♥♥♥♥♥♥♥♥ yourself. Remember, do not ♥♥♥♥ yourself. Just follow the standard teamfight procedure.

1. Stand the ♥♥♥♥ back
2. Use Spirit Form
3. Aim Wave of Death at area in which teamfight is taking place
4. Mana leak enemy hero most likely to ♥♥♥♥ your ♥♥♥♥ in
5. Use Blinding light on enemy right click hero
6. Repeat steps 3-4 until you either a) win or b) get rekt horribly

You may need to dispense manas and health if you have a mek at some point during the fight. If you have a pipe, use it as well.

Tower Defense ♥♥♥♥♥♥ Flash Edition
Valve listed KOTL as a pusher despite the fact his skills do no damage to towers. Oh well. Using the power of standing back and spamming Waves of Death, you can siege a tower pretty hard, forcing all defenders to either leave the tower alone or take lods of edamage. Creepwaves mean ♥♥♥♥♥♥♥♥♥, as a fully charged level 4 wave of death will kill most creeps (and the siege creep, which is immune to most magic.) The same tactic can be used to defend a tower from enemies who are trying to destroy it. Remember to avoid standing still in the same place for ages because if your enemies are smart they will catch on to your scheme and go round and kill you.

HURR DURR WHAT DO I BUILD NOW I AM PHYSICALLY UNABLE TO THINK FOR MYSELF
Assuming you have Mek and are taking care of wards, there are a number of bigger items you could aim for.

Am I winning hard? Boots of Travel.
Are they ♥♥♥♥♥♥♥♥ on me and everything I love? Euls or Forcestaff.
Do they possess all the magic damage of the universe? Pipe.
Do I hate towers and wish eternal death upon them? Necrobook.
Am I earning enough money to finance a solid gold statue of myself? Scythe.
Are we winning but they are still ♥♥♥♥♥♥♥♥ on me and everything I love? Shivas.

6.81 ADDENDUM
ALTERNATELY YOU CAN GO BUY AGHANIHMS AND ♥♥♥♥ ALL OVER EVERYTHING WITH YOUR MAGICAL HEALING HORSES PERMANENT ULTIMATE AND LEGIT MAPHACK THANK YOU ICEFROG FOR THIS GLORIOUS BOUNTY

Fun is a restricted quantity
Sadly, towards the end game is where you stop being a massive ♥♥♥♥♥♥♥ that ♥♥♥♥♥ waves of death everywhere and just another squishy support. Fortunately, your ability to accquire items using the aformentioned waves of death ensures you still have good items to make your presence felt (unless you fed horribly). The Waves of Death still will take out or cripple creep waves to the point where one hit will kill them, so you aren't completely useless. Yet. If you are still hemorrhaging money, consider the other items mentioned above.

Proper Use of Recall
Should you ult for the use of recall?
If: someone on your team is in enemy territory and/or is going to get rekt horribly : Yes.
Else: No

oh ♥♥♥♥ we threw horribly and now we're going to lose what do
If you are going to lose, don't feed bad. You had six buttons to press, and that ♥♥♥♥ is hard. Fortunately, while by this point enemy heroes can shrug off your waves of death, creep waves cannot, so you can just continue to hide in your base and spam waves of death, dragging the game out for another 50 minute to ensure that no one has any fun. ZE FUN IS VERBOTEN.

CARRY A ♥♥♥♥♥♥♥ TP SCROLL. AT ALL TIMES. TWO OF THEM. THREE OF THEM. WHATEVER.
JUST ENSURE YOU HAVE SUFFICIENT TP TO TRAVEL TO ANYWHERE ON THAT REQUIRES ATTENTION UNLESS IT'S ON COOLDOWN OR YOU HAVE BOOTS OF TRAVEL. BUY TP SCROLLS. BUY THEM.

Some items I forgot to mention, like Tranquils, Drum and Urn are good pickups too. Use your brain and assess the situation and decide whether they would be a good investment or not.

In conclusion this is an excellent guide please give me money I work hard for the money so hard for the money oh something come on gimme lots of money
