Fire Vikings passive has been fixed and now requires significant accuracy. The invincibility buff shown above in Dragons B10 has also been changed to an immunity buff. He’s still good for B8 which still uses the invincibility buff, but no good for B10. Bella (light inugami) is a far better choice if you need a buff remover.

just in case you’re still curious on this:
the +healing% in the skillup is off the original healing%. 10% of 15% is 1.5%. So it does adds like he said.
15% + 1.5% + 1.5% + 1.5% = 19.%
Healers would be WAY too powerful if it was not like this.
In case you are wondering, +damage% is how you were thinking.

It clearly says +10% there, where’d you get 1.5 from?
and it is 45% heal every 3 turns.

Oh, use Bella instead.

Its 15% +1,5%+1,5%+1,5% = 19,5% heal every 3 turns, not 45%

Actually, Geoffrey’s second skill does less damage as his HP decreases. I wish it was like Ramagos’ Clean Shot. That would be awesome. Unfortunately, we are not that lucky.
