Nature's touch is not removable after ascension lvl 3. The Boss at the end has increased attack when attacking enemies with no buffs active. When I use natures touch it applies an attack buff for two turns and should reduce incoming damage as all my forces are buffed. I have noticed that if an attempted removal of the buff occurs, the damage calculated appears to act as if no buffs are still applied to my team. For example when buffs are applied the damage usually ranges between 1-3k when the buffs are not present the damage ranges between 5-6k. At first I thought maybe it was only when crits occur, this is not the case.
