Bezhukov: You invest the loads of levels so you can fascinate at dc 30, dipshit. And get +5 to skills. And +3/+3 on all attacks from everything (+4/+4 at lvl 16). And shaken on everything at the start of every battle. And fear is you want it. And +4 straight up on dodge/saves late when you need it.
InEffect: +2 over what you already have at 5. Skillchecks don't matter.Any proper party has enough for everything. Will DC30=5% for most mobs. It's as bad as it sounds. Will affecting spells and abilities are bad and you should feel bad.
Bezhukov: Ekun provides tons of damage. He's already got most of the archery skills he needs. 8 levels of huntmaster costs two AB. That's it. Community on Ekun is worth it for the outflank on Okbo alone. He can also cure fatigue from his first level of huntmaster.
InEffect: You lose AB and damage from it and you will end up with a bad ranger and a bad huntsmaster. 8 levels in huntsmaster alone will kill your DPS faster than anything. You have to have 15 levels in ranger for 4d6 sense vitals, you have to have 2EA for an extra arrow. That leaves 3 levels for either huntsmaster to buff your pet(bad idea for unfair. It will be hit and killed anyways) or V3 for mutagen and 3d6 sneak.
Bezhukov: Attacking will is great all through the midgame and its easier for her to land her spells since she keeps those mobs shaken all the time. I've also got a high DC Archon's Aura up at all times for another -2.
InEffect: Midgame mostly consists of undead. GL attacking will of those. Glitterdust and grease are the real deal there.
Bezhukov: Her evo spells own casters who have low fortitude, with the damage also triggering a concentration check. Your achers and chargers can clean up from there as necessary. Her covering ill and fortitude frees up you wiz/jubilost to target reflex.
InEffect: Stinking clouds. No need for gimmicky spells that stun for a round(if at all). Bards should prebuff and tank. That's it.They are totally unable to reach DC's that are needed for unfair.
Bezhukov: If you're threatened (i.e. in melee) you'll trigger a concentration check whether you're hit or not. Try it with Harrim's touch of chaos some time. As pure bard her images last long enough to keep them up when needed, so she can get to less than 1.25% if needed, but she shouldn't draw aggro.
InEffect: Doesn't matter if you get attacked If enemy has 1.25% to hit you. Anything that doesn't have untouchable AC, invis and mirror image should not be in melee to begin with.
In conclusion, play more of the game instead of spewing nonsense and trying to insult your way to winning an argument. That will get you nowhere.
You're the one who led with insults. Just because you don't know how to debuff enemy saves, that doesn't mean no one else does. Obv don't target strong saves, but there is all kinds of stuff throughout the game she can reach if you're properly debuffing saves. Not everything will stick - that's unfair - but enough will if you properly control the battlefield.
No need to debuff for Trolls and Owlbears and Gobs and other random big dummies. Of course will isn't for undead, but other classes attack reflex better than bard. I might consider not even taking her for Vordokai's Tomb. But that's only one part of a huge game.
As for Ekun, Sense Vitals is per round and he's never getting enough casts to keep it up all the time. If you don't understand how important getting Outflank on Okbo is maybe you should play the game more. Seriously, your original build recommended cutting Lingering, which is the most important bard feat, one of the most important in the game (imagine rage with lingering). Makes me think you're resting every other fight.
Okbo might get hit and killed if you don't know how to buff him properly (Jubilost is best for Echolocation and shield, but he gets to 50 AC without it) and debuff your enemies. Of course when you play six soloers no one gets around to debuffing so I could see how he might struggle for you.
And then ghosts eat him alive because his touch AC sucks. Most of your thinking is built around endgame, but 90% of the game is getting there. That's why you don't know how to play Linzi and Okbo, because they're non-entiies at the endgame.
