Level 1 is tough on everyone, tho. None of us are really that great at anything.
But hey, let's look at some numbers!
Culpa/+1 hit, 5 damage avg, divine spells (7 hp and 19 ac)
Ithra/+0 to hit, 3 damage avg [6 with SA], sneaky (8 hp and 12 ac)
Osirio/+3 to hit, 6 damage avg [7 with Guisarme], debuffs (13 hp and 16 ac)
Ava/+3 to hit, 11 damage avg, divine spells (11 hp and 16 ac)
Ari/+1 to hit, 3 damage avg, Spells and Songs (7 hp and 14 ac)
Now, see-Ari's got the lowest of us...unless he's doing his song of courage. It affects everyone, equaling +5 damage over the whole party-minimum. It also increases the chance of hits.
That's what is called a "force multiplier".
Now look at my char. He does only slightly higher than average damage in the party. He cannot cast spells, and his hex is only useful in a roundabout way, but not "excitingly"-if an enemy misses the attack, who is going to notice?
Ava will always outdamage him, and she can cast spells already. Culpa and Ari can also cast spells. Ithra can probably out-talk and certainly out sneak him-Osirio has few unique skills, except for intimidate. His AC is good, but Culpas is better. He has a little better HP, so he can get attacked alot more. Yay?
Not everything is damage, or we could all be happy playing clones of Ava.
You'll be happy when you can buy a wand of flaming sphere!
Maybe spears, throwing axes, or javelins would be more to Ava's taste? She'd use her STR bonus for damage rolls on them.
Or maybe she could enchant her maul with returning one day...
I suppose throwing axes and javelins would fit, but it's kind of cowardly to kill at a range you won't even get splashed by their pulverised brains. She has a tower shield to protect her from such cowards, anyway.
It's more of a "they are a hundred fifty feet across the bottomless chasm, shoot them with arrows!" thing-and "oh my Gods that thing is made of living vomit and acid, let's not go into melee!"
Honestly, there's some stuff you don't even want to get close to.
Osirio must be teaching Ava the tactics, it is seeming!
