Taking inspiration from various "fantasy lore" sources, I'd like to start a discussion about creating new named, epicable Dwarve Waraxe (or perhaps one to be added to the challenges, in multiple level versions).
Base Stats:
[W] = d12
critical profile: 20/x3
base DR bypass: Mithral, Silver, Slashing
Mithral is rare metal, and in various fantasy writings secret of forging it belonged to dwarfs.
Dwarfs are known to be (in general) bound to their families/clans. They take pride in standing in line with their ancestors. Hence the name "heirloom" and dwarf-focused stats:
Dwarven Weapon Mastery: when wielded by dwarf, this weapons base critical multiplier is increased by 1.
Dwarven Waraxes (along with bastard swords) in DDO are unique weapons, in the fact that they can be proficiently wielded with THF and TWF characters. I'd like to see stacking weapon effect adding chance to bash with shield.
Another thing Dwarfs are well known for, is their good balance.
I'd add effect analogous to Chimera's Ferocity;
for non-epic version:
1 dragonmark of warding: balance +5, Shield Bashing +10%
2 dragonmarks of warding: balance +10, Shield Bashing +20%
3 dragonmarks of warding: balance +15, Shield Bashing +30%
for epic version:
1 dragonmark: +7, Balance +15, Shield Bashing +10%
2 dragonmarks: +8, Enhanced Balance +5, Exceptional Shield Bashing +10%
3 dragonmarks: Unhindered movement +20% (effects reducing movement speed such as cripling, illusionary chains, slow spell or defensive combat stances are 20 precent points less effective), Exceptional Shield Bashing +15%
Greater Dragonmark of Warding: +10, Immunity to knockdown, Exceptional Shield Bashing +20%
Another effect I'd like to see here, is "Alignment focus":
When wielded by good character, becomes "of Righteousness". When by Lawful, becomes "of Lawfulness" (+2 to hit and to damage vs chaotic foes, bypasses DR/Lawful). When Chaotic, becomes "of Chaoticness". when by true neutral, "of Superior Stability". So, chaotic good character wielding it against Lawful Evil enemy would get +4 to hit/damage.
