Allies can move into and occupy space. If any allies occupy spaces with Divine Vein (Ice) applied, attacks targeting those spaces will hit the ally over destroying the Divine Vein (Ice). (Divine Vein effects do not stack; replaces any existing Divine Vein effect; Divine Vein effects applied simultaneously cancel each other out. Does not count as defensive terrain. Does not trigger in Pawns of Loki.)	300	Mend

Notes

• The stat increase that can be applied by Ice Lock is considered a  Bonus.
  • Any 【Bonus】 effect on a unit, including  Bonuses, lasts until the start of that unit's next phase. If  Bonuses are acquired during the enemy phase, they will disappear when the next player phase begins.

•  【Divine Vein (Ice)】 adds effects to spaces regardless of the terrain of those spaces.
  • Divine Vein effects do not stack with each other. if a Divine Vein effect is applied to a space where another Divine Vein effect is active, the previous Divine Vein effect is overwritten.
    • Divine Vein effects applied at the same time cancel each other out, leaving the overlapped spaces without a Divine Vein effect.
  • Divine Vein effects do not apply to spaces with unbreakable walls, unbreakable structures, and other unbreakable terrain.
  •  【Divine Vein (Ice)】 does not apply to spaces occupied by foes, spaces with other breakable terrain (excluding  【Divine Vein (Icicle)】), and warp spaces in Rival Domains.
  •  【Divine Vein (Ice)】 can prevent the enemy reinforcement from spawning in from  Calling Circle (O) or  Calling Circle (D) by occuping the same space as the structure and any nearby spaces.
  •  【Divine Vein (Ice)】 is not considered defensive terrain, so  Queensblade and  Breezy Spear will not disable it's effects.
  •  【Divine Vein (Ice)】 will not trigger in Pawns of Loki.
  •  【Divine Vein (Ice)】 acts as a breakable structure (with 1 HP) for foes.
  • Allies can pass through and occupy spaces with  【Divine Vein (Ice)】, but attacks targeting spaces with  【Divine Vein (Ice)】 will prioritize allies on those spaces (if any).
  •  【Divine Vein (Ice)】 can be destroyed by  Resolving Flame after start-of-turn skills trigger.
• Ice Lock applies the  Gravity status effect.
  • Any 【Penalty】 effect on a unit lasts until that unit takes an action. If the unit takes multiple actions in a turn, they will only have  Gravity for their first action.
  •  Gravity has priority over  Mobility increased and  Gallop.
