Level 5 Wizard: How to Kill a Barbarian

[Troacctid]

If I were preparing a barbarian for this, I would be looking at something like:

Raptoran Barbarian 5

Ferocity, Serpent Totem

1. Touchstone (Catalogues of Enlightenment: Patience domain)
3. Air Heritage, Improved Grapple (B)
5. Improved Initiative (B)

70-foot fly speed makes it hard for the wizard to kite and allows a charge in the first round. Patience domain shakes off the wizard's first big hit; hopefully they won't have a second one prepared. Improved Initiative and Ferocity give a decent chance of going first. Grapple the wizard to prevent casting, and if they don't have Abrupt Jaunt to escape, it's hopefully over from there. If they do have a way to counter the grapple, you'll have to trade blows and hope that your attacks are enough. Weapon familiarity with footbows is also an underrated benefit of raptoran, since you can add 1.5x Strength to the damage; readying an action to disrupt spellcasting with footbow attacks could be a viable backup plan.
