Shadowfiend was an incredibly rare Priest summoning skill.
Its strength wasn’t in the bit of damage that it could deal, but rather in the effect of the Shadowfiend.
Every time the Shadowfiend successfully attacked, the caster would regain 10% of their MP. If they were lucky and got in 4 or 5 attacks within those 15 seconds, the Priest would be able to recover around half of their MP.
With this skill, March Rain’s sustain would be much better, and she wouldn’t have to run off while fighting Bosses to recover her MP.
Shadowfiend was worth a lot of money and although it couldn’t compare to Lu Li’s Vanish, it was much more valuable than Remnant Dream’s Tame Beast. This sort of skill could ensure continuous healing for a team and many unions would be willing to pay a high price to create a self-sustaining healer.
Lu Li thought about it for a long time before painfully giving the Skill Book to March Rain.
