Hey all
Recently started playing dnd online and dnd at the same time roughly an i play wizard on DDO
My query is seeing as wizards from what i gather are the only class to heal battle forged, would it be worth wile multiclassing as a cleric to be come a better healer?

The very simple awnser to this is no, you can heal a warforged with Repair spells, which are arcane spells and only a wizard or sorceror can have.

A side note, it's not entirely true that wizards are the only class to be able to heal a warforged, they can only heal them at 100% success, but warforged can also be healed by clerical spells, but they have a 50% penality by doing so.

Mostly, as a wizard, you won't end up very often as warforged healer in a group, most of the times, you will be using your spells for crowd control, buffing the party and damaging your enemies, and if you want your spells to have the highest possible chances to land on your enemies, you need to stay pure class as much as possible, each level of wizard will increase the difficulty of your spells to be resisted.

Also, the warforged class, as they level up have enhancements to make them more healer friendly and even items so they get a higher benefit from clerical spells.

Wizards and Sorcerors both can pick up the repair spells. Unless the sorc is a wf though
they generally don't. I wouldn't recommend multiclassing wizard with anything except maybe
rogue. And I'd only do that if you have it planned out meticulously.
While playing a wizard(or sorc), i generally heal wf with wands and save my sp for
shaping the battle. At least until the reconstruct spell is available.

hope this helps a bit.

Just follow what Hakushi and herzkos said... cleric is a bad choice to multi-class with wiz, and rogue can be awesome to multi with as long as you keep it to 1 or 2 levels and plan it out very carefully from before the creation of your character.

Just focus on one job only..
