Ninja > Scouts, disarm traps, noticed them. He does it, but sometimes during combat instead of killing the blinded boss, he chooses to hit a goblin for 3 turns doing 1d6 damage > took him 3 turns to kill it. Or he doesn't look for the flank with the Slayer
- Ok, if the Ninja isn't trying to use the advantages of his class and of what his party do maybe there is a problem. As widard you do your job and you debuff and control the enemy, your teamates should do their job and take advantage of your spells! He has Sneak Attak, for what reason in the universe he does not use it when he can? Maybe he would feels better with another class, one less dependant of battlefiled positionament for damage.
Also the concept of priority should be clearer : if you do not exploit the advantage to quickly eliminate the boss you're giving them a chance to do more damage later.
Slayer > Tanking? Doing damage without flanks? He's at 1d8+4 for Longsowrd and 1d4+2 for Shield, without Studied Target+Sneak Attack
- See above. Studied target and sneak attack are your best weapons. You want use your weapons. Why not?
Oracle > he can heal, great diplomacy, Summon
Me > Glitterdust, Grease, Color Spray. I do sometimes use Familiar to scout a little
Consumables? It would be too much if someone buys a Healing potion. I bought a wand of Vanish, not super effective, but I can position freely, or escape.
No one has Alchemist Fire (I used to have 2, got used), or Smoke Sticks, or Caltrops.
Afaik, I'm the only one using scrolls.
- this can work : alchemical items are very useful and can be easily found . A good investment could also be a wand Ray of Enfeeblement , to lessen the chance to hit and to damage of the biggest enemies.
DM kinda ruled that Achievement Feat can go away, I'm not sure. Anyway Oracle could potentially do damage only with Spells, his STR/DEX don't allow it.
- Is perfectly possible but these levels to do this it is necessary a minumun of inventive and strategic thinking . One suggestion would make him Raise wisdom ( Scroll of Wisdom owl ? ) And let him learn the Command spell. With the command " knocked down " for example from +4 to shoot simultaneously to hit your allies and if he gets up causes attack of opportunity, which means attacks and damage free . Alternatively . Or similarly positioning itself in a certain way and giving the order " approached " the result is that he cause attack of opportunities by EVERY ally, including any evocations ... 3-4 + free attacks. Interesting is not it? and by fully respecting the requirements under the feet.
