Hydra
Head lines in health points
Three Heads costs the Hydra a head below 66% and 33% Max HP: about 8,520 and 4,260 of its 12,910 health on difficulty 1, about 10,450 and 5,220 of 15,830 on the other two. At 15 HP/S per head it regenerates 45 HP/S until the first line, then 30, then 15, so on difficulty 1 the first 4,389 damage meets the fastest healing.
Venomous Bite by difficulty
Only the Hydra gains offence on difficulty 2: its Attack and Attack Speed, always equal, go from 58 to 62, then to 74 on difficulty 3 with health unchanged. Venomous Bite deals 150% of Attack, 87, 93 and 111, and inflicts 2 Poison plus 1 per 20 Attack for each remaining head.
Burst while all three heads regenerate
Shard Power Extractor has a 2,500 minimum, and 10% of the Hydra's Max HP is only 1,291 to 1,583, so the minimum lands: 19% of the difficulty 1 bar, 16% of the others, over half the 4,389 before the first lost head. Critical Ascendancy, from Crit Rush Assassins, targets the opening: after its 100 Crits quest, each hero's first auto attack against each enemy gains 1,500 Crit and Stuns for 2.5 seconds.
Hydra's Healing gives enemies 1 HP/S per 150 Max HP when combat begins, so an enemy needs only 2,250 Max HP to regenerate like one Hydra head. The floor 6 Hydra Fight event stage reuses both abilities on 26,350, 33,310 and 33,310 health and Attack 138, 138 and 165, putting Venomous Bite at 207, then about 248.
