Suggestions for the following Pretender, please?

[Ravagemk2]

Presently testing a Nataraja with Caelum.

Present equipment is:

Weapon 1: Death Arena Trident
Weapon 2: Frost Brand (used to be Ice Sword)
Weapon 3: Frost Brand (used to be a Blacksteel Towershield)

Headgear: Spirit Helm
Armor: Chainmail of Displacement
Footgear: Winged Boots
Misc. slot: the pendant that gives airshield vs arrows.

Making that thing fly has done wonders, as it's effectively at the opponent's throat as soon as it gets a turn.

The pendant is not so much against the opposing arrows(I've got the guy set to target archers), but more the 100+ Caelum Archers he's got tagging along

I'd probably have given him a charcoal shield, but there is one...tiny...problem.

I've already forged a ring of waterbreathing for when this guy has to take anything underwater.

Or would shambler armor be better in this case?
If so, I can still keep the ring, as I've got a few site hunting mages who'd need to check said locations too.

You'd think that at 10% chance of a fire skill when you recruit an Eagle King, you'd have gotten it after recruiting 20+ of the guys x.x

My research on the other hand, is going like a bullet train
