A Lovely Present

Rogues learn an ability called Surprise Bomb (around lvl 37). Place a Heal Box in your troop's formation and have the Rogue sabotage it with said ability, then walk over it.

结合楼上。ROGUE学到一个叫SURPRISE BOMB的SUB技能(大概37级学会，可在SKILLS界面确认一下)，在FORMATION界面设置一个HEAL BOX(我有四个，忘了怎么来的，获取难度应该不高)保存阵型界面，然后进入战斗后对HEAL BOX使用SURPRISE BOMB，自己踩过去，跳杯。
