What the fuck?4e Multiclassing really isn't that bad; and a few simple house rules make it a lot more palatable
Seriously, a multiclassing system where you won't even see your first daily ability until the game is one-third of the way over and after you blow two feats on it?
We had a name for this dubious option back in 3rd and 2nd edition: it's called USE MAGIC DEVICE.
That's because you didn't. If you weren't a sword-based classed then you indeed did not haphazardly multiclass. You took a goddamn prestige class.But then, you couldn't haphazardly combine any two classes in 3E either. And honestly, there weren't particularly good gishes in 3.5 core either.
And the reason why there weren't any good gishes was because 1) wizards already could outperform fighters with their swords without even multiclassing and 2) wizards' nuke-em spells were better anyway,
Initiate of the Faith: Control Wizards, Rangers, and Pole Fighters meet the requirement naturally. Toughness gives 5 hp per tier, healing word 1/day gives 3.5. Toughness increases the amount healed by surges, while healing word increases the ease of surging. A decent filler feat.
Warrior of the Wild: This is it, this one is made of win. As printed, Hunter's Quarry 1/encounter makes those hydra grinds *way* more tolerable. The errataed, 1 round version sucks. That's okay though, because this feat allows you to learn *perception*. Almost anyone can take this feat, and should strongly consider it.
Hahahahahahaha! That's so funny.Student of the Sword: Endurance could be a good skill to have, but I'm having trouble finding builds that both need strength and can use the mark effectively. FAIL
Oh, wait, you're serious. Let me laugh even harder. Hahahahahaha!
If you really really want me to, I can demolish these 'good' options. They're massively underwhelming feats even for 4th Ed.
Seriously, your argument for using most of them is 'they're like Skill Focus, but once per round per day you get a bullshit benefit!'. I don't even know what to fucking say to that.
