| Sustained Debuff
- Sustained Debuff effect has an 80% chance to Debuff the target at the end of the turn for -1 ATK/DEF. Duration is 3 turns.
- If the target's Stat Total is Positive, the Sustained Debuff effect is guaranteed to be applied to the target.
Rion is a rather curious Blue Slash card. Unlike Emperor before him, who specialized in just straight-up damage, Rion's gimmick is applying a Sustained Debuff effect on the enemy, possibly debuffing their ATK & DEF every turn for 3 turns. Making it even more appealing is that if your target's Stat Total is Positive, then the effect is guaranteed to be inflicted.
Of course, this does make Rion valuable against more difficult bosses who tend to buff themselves a lot. Though it's worth noting the most difficult foes will often buff for more than the debuff inflicts. Still, Rion can be useful for keeping foes' Stats under control.
Rion has a rather curious and good Sub Skill! First off is an unconditional 35% Skill Boost to any Slash card.
But on top of that, for every 20% HP missing, you gain 3% Accuracy for your attacks. (Which is 75% equivalent to a +1 AGI boost.) While it seems a bit quirky, it can become very handy when dealing with foes who love to increase their AGI or lower yours.
