Dark Monte (Monte)

Monte is a lot more useful than he seems and is HILARIOUS in RTA. 
I use him in Necro b10, Dark Rift, and RTA and have him runed vio/revenge, spd/hp/hp.
 A couple of things that make him better than he seems: 
1) His AI is really intelligent. It never uses his 3rd skill on a damaged target, so the AI will never heal trash mobs in dungeons. Also, while his mechanics preventing him from using the 3rd skill on bosses may seem like a negative, its actually not. In necro, this means he consistently uses his multi-hit skills with good turn-proc chances on the Lich's shield, and when your mob is stolen, he uses his 3rd immediately if they are undamaged. Because of this, you want to tune him to move first on your team so at most a double-6 (2% chance) does nothing (e.g never heals). 
2) In Dark Rift he can't use his 3rd either, so he basically just spams all the multi-hits and in groggy state puts on a ton off debufs. He pairs really well in a team with Xiao Lin or other multi-hit creatures that do extra damage based on number of debufs.
3) In RTA (I flip between f3 and c1 in RTA) no one ever bans him. No one expects him or cares. But here his 3rd skill really shines. Again, you want him to be the fastest unit so he won't be likely to heal. Tactically it seems to surprise the heck out of people when he takes 80% of a Mo Long/Rakan/Seara/Artamiel/ other RTA threat's HP right off the bat, especially through shield and will runes. Because it is an HP re-balance not damage (like the opposite of Chasun's ability) it doesn't proc nemesis, revenge, wind monkey's passive, Artimiel's passive or any other ability of the sort. The fringe benefit of this is that more often than not, after a successful Destiny Dice proc Monte becomes everyone's target, so with enough tankiness more standard threats can do their thing. Even without his 3rd ability all of his debufs are pvp relevant so he doesn't lose value after turn 1. 
All in all, he has quickly become one of my favorite units and I don't regret building him at all.      

Nice review. I understand S3 works like Harmonia´s one, but without heal and based on a dice roll. Seems interesting, I´d love to have Monte to play with him, as I really like the thrill of the randomness in this game.

KainMH3, now you have the opportunity you wish for from current HOH! If you happen to play with this guy, please let us know what you think. I still can't see if he can be of value in PVPO if you don't have a Mo Long, which is my case.

I don't have a great RTA team yet, so I ended up using Monte there. Combo him with a Mo Long, using Monte S3 on a target (hope for the best) into Mo Long S3 and it can usually delete any single target. Works great as a scare tactic, the problem is then is waiting for both cool downs to come back to do it again, so either you build a team with enough tankyness to carry the two through (I use Louise and Taranys for this reason) or you aim to kill their damage dealer up front and hope their other mons won't be able to touch you.
