Hi,
According to this 60 is the maximum you can inflict with the catapult:
http://elementsthegame.wikia.com/wiki/Catapult
1. Ew, wikia. Use the Official Wiki (
http://elementscommunity.org/wiki).
2. The table uses the old formula, where, as HP tends to infinity, damage tends to 75. A 499 HP creature would do 65 damage.
Balance:
Catapult does more damage, the formula uses now 100, instead of 75, as the maximum possible damage.
The new formula is "damage = (100 * HP) / (100 + HP)"
As HP tends to infinity, damage tends to 100. A 499 HP creature would do 83 damage.
20 HP: 17 damage, 22 frozen
25 HP: 20 damage, 26 frozen
40 HP: 29 damage, 38 frozen
45 HP: 31 damage, 40 frozen
