Krampus is one of the monsters I had ages ago and haven't really moved his skills around since.

However, I don't run either of the 2 random neg effect skills (plus poison/burn). I figure I really need both of them, as well as the single freeze and the AOE freeze.

Opinions?

I also run 2 level 4 speed and 1 level 5 life rune on Krampus.

I run the AoE freeze skill, both single target skills (one burns, one poisons, both do 2 random effects), and the single target skill that causes bleeding. I run with all speed runes. I should note that my runes are not a high enough level to warrant the 1 speed, 1 strength, 1 life strategy. Three level fives is what I have.

While he has the AoE freeze skill (and it's usually my first move with him) I don't use him a strict denier. I use him a bit as an all-arounder. He can freeze everybody and he can stack some torture status effects on select enemies, sapping them of their life. And you get the bonus of random effects thrown in there.

When I use him (which isn't as often as I once did), I usually have another denier in the team too and some high damage dealer. Krampus and the other denier keep the enemies tied up while the damage dealer and Krampus kill them off.

Life rune? He used to be the fastest monster in the game (except for the 3 rarely used ones) and with an AOE freeze and single freeze, he's undoubtedly one of the best deniers at that time. Until the day when SP implements the recently freeze, he's still very functional (except in winter book). 3 best speed runes on him.

Yes I run the same movesets that includes burn and poison.

He's now 11th for speed in the game. If he goes first, which he usually will, if the enemy team has a denier like Caillech, Cavenfish, Zimnyaya, or monsters that have Tough, Bulwark, or Artifact, your freeze abilities are a lot less effective.

In a battle where the enemies don't have immunity to freeze or reduced chance of getting frozen, and your attackers are strong enough to kill off one or two of the enemies within that one turn, then yeah, he can be your main denier. But I find that I need a denier (or deniers) who can deny a whole enemy team for at least 2 rounds. And, like I said, I just like having options.
