NHF – new heroes for Heroes V 3.1.

Can you suggest heroes? If so, here's my idea:)))

Name: Alexander
Faction: Humans
Specialization: Sheltered by an Angel

Ability description: Once per battle, the hero can summon his angel, who will protect him. The angel's hit points will increase with the hero's level. Initial hit points: 100.
Level 2: 110
Level 3: 115
Level 4: 125
Level 5: 130
Level 6: 135
Level 7: 140
Level 8: 142
Level 9: 148
Level 10: 150
Level 11: 153
and so on...
Basically, with each level, fewer hit points are added.
