Sorry to be the grumpy one but although there are item spoilers in the subject be careful with referring to ToB items (first post Pyrenk)
The easiest thing of course is fire/red dragon theme
Berserker
Dragon Helmet
Red Dragon Scale
Dragon Slayer
Dragon Scale Shield
Ring of Fire Protection
Ring of Gaxx (it's also red
)
Halberds (Dragon's Bane and Dragon's Breath) as secondary weapon
maybe dual to a mage to be able to cast a certain high level spell in ToB.
