Water Lightning Emperor (Bolverk)

Bolverk, the Water Lightning Emperor is a great nat 5 monster in Summoners War.

Just like the other Lightning Emperors he is based on Knowledge mechanics.

He has Learn Knowledge as second skill, that means that he gains knowledge if himself or the enemy gains a beneficial effect.

So, for example, if he is against a Woosa that buffs himself and 2 other allies with his third skill (immunity plus shield), Bolverk will gain 5 knowledge (instead of 6, since knowledge is capped at 5).

His third skill is a single target skill and it will deal damage proportionate to your knowledge, 10% of enemy's current HP per knowledge point; if used with 5 knowledge it will deal 50% of enemy's Max HP instead.

This skill very similar to Mo Long's third skill and will kill monster below 50% max HP with oneshot.

Moreover, with this skill you will heal all allies by the decreased HP.

Since the damage output in entirely based on enemy's stats, since Bolverk can not increase his knowledge by killing enemies and since this skill changes a lot if it's used at max knowledge, it's better to build Bolverk tanky, with lot of resistance, speedy but not Violent.

He is very good to use in PvP, both defense and attack and in all Guild content, also because of his leaderskill with 44% HP in Guild; he's even good in Labyrinth but not the boss stages, since his third skill doesn't work against bosses.
