Well, I certainly put my foot into it. Last time I wrote here, I (sarcastically) pointed out a distinct lack of Artificer/Barbarian multiclass characters. Immediately upon finishing writing that, the first thought that entered my mind upon logging into DDO was, “Let’s give that a shot.”
It’s fun, to say the least, though I do have some interesting observations (possibly as to why this mix isn’t overly popular)
1) An artifer’s infusions are treated as spells in the game. Therefore, you can’t cast them while raging.
2) You can’t set the runearm to automatically charge while raging. Instead, you have to keep triggering the bound key (I use the default Alt personally), but it will keep charge if you had been charging it before going into a rage.
3) The Battle Engineer tree has useful enhancements, if you are willing to use a hand-and-a-half weapon with a runearm. The other tree isn’t near as helpful.
4) Choice of runearm matters greatly. Thought Spike is great for attracting enemies at a distance, but Flame Warden is better for actually being in melee. I also have Chulchannad’s Claw, though I haven’t tested it yet. I much prefer the Flame Warden over the Thought Spike, though the force damage is nice.
