## Bosses
- Reduced base armor and base magic resistance values of all bosses, minions now have 0 base armor and 0% base magic resistance
- Minion is now a creature type like Reinforced. Represented by an ability. Whenever a spell deals damage to another unit, all minions gain 50% damage resistance to that spell for 1 second.
- Champion is now a creature type like Reinforced. Represented by an ability. Champions take less damage from abilities that deal maximum health damage. The damage resistance formula is 100*(1-1/Players), for a total of 0/50/66.6/75/80/83.3/85.7/87.5/88.8/90% (NOTE: Due to DOTA2 limitations, currently this affects all units, but it'll be changed to only be vs bosses eventually)

## Abilities
- Maximum health abilities returned to vanilla values, no longer tuned down.
