Spur

NecrobinderSkillUncommon
Retain.
Summon 3.
Osty heals 5 HP.

Has Retain and does two things in order.

  • Summon: Summons 3; if Osty is not out he appears with 3 Max HP, if alive his Max HP rises by 3 for the combat.
  • Heal: then he heals 5, capped at Max HP.
  • Fresh summon: the heal is wasted, since a 3 HP Osty is already full; the value is on a wounded Osty, 3 more Max HP plus 5 healing.
  • Buffer: while Osty lives, unblocked attack damage aimed at you is redirected into him, so healing him is healing your buffer.
  • Upgraded: Summons 5 and heals 7.
