VOTE FOR IO!!!

Elementalbuilder now uses IO Model instead of Invoker.
All armor types are now basic, because soft type doesnt exist anymore.

0.7.12

## General Changes

- The final duel now decides the game as each team's king teleports to the middle of the map to settle things once and for all. During the final duel, kings have HP reduced by 30%, Health regen reduced by 20%, and a damage penalty of 15% of base damage.

- Setup time before duels is now less than for other rounds, 10 seconds instead of 35.

## Builders

- Elemental Builder rework: Gods now upgrade from Elementals instead of Benders (Benders are the basic summon). Their upgrade costs have been decreased so they still have the same total gold cost, but the upgrade still requires one additional food.

Old:

Waterbender (40) + Upgrade to Watergod (180) = 220
Thunderbender (65) + Upgrade to Thundergod (310) = 375
Earthbender (70) + Upgrade to Earthgod (390) = 460
Firebender (75) + Upgrade to Firegod (450) = 525
Voidbender (100) + Upgrade to Voidgod (500) = 600

New:

Waterbender (40) + Upgrade to Waterelemental (85) + Upgrade to Watergod (95) = 220
Thunderbender (65) + Upgrade to Thunderelemental (130) + Upgrade to Thundergod (180) = 375
Earthbender (70) + Upgrade to Earthelemental (200) + Upgrade to Earthgod (190) = 460
Firebender (75) + Upgrade to Fireelemental (180) + Upgrade to Firegod (270) = 525
Voidbender (100) + Upgrade to Voidelemental (90) + Upgrade to Voidgod (410) = 600

- Fire God attack range from 600 to 260, and supernova trigger range from 100 to 300. (Fire God should use its ability much more now).

## Waves

- Wave 13 Tidehunter: Armor reduced from 15 to 12

- Wave 20 King: Attack Time reduced from .9 to .8

- Wave 22 Earth Spirit: from 4 armor, 550 HP to 6 armor, 500 hp

- Wave 23 Kunkka: Count reduced from 12 to 10, bounty from 5 to 6, wave-end reward from 49 to 51

- Wave 25 Tiny: Armor reduced from 15 to 12

- Wave 28 Rubick: Armor from 5 to 3, Magic Resistance from 0 to 15

- Wave 30 Dragon: Attack Time reduced from .6 to .4

## Misc.

- Fixed Return to Sender not working for Dire.

- Upgrading a unit will now select the new upgraded unit.

- Leavers now cannot earn income or spend tangos.

- New Russian translation provided by Fresh-_-War

- Actually apply the fix to send creep aggro

- Fixed send creeps being aggro-able before being moved to lane

0.7.11b

- Each team can only have 90 send units in their "pit" at one time. When an additional send is purchased, the cheapest will be destroyed. (You still earn income for sends that are instantly destroyed in this way)

- Purchase cooldown for the first row of units has been removed. (kobold, hill troll shaman, hill troll warrior, and harpy)

- Fixed not being able to build a unit quickly in a space where a unit was sold.

- Fixed being able to build units between waves. (Previously you could do this by issuing a build command during setup in such a way that the actual spawn would happen after wave starts, creating a unit that would never "unfreeze" until the next wave)
