I'm starting to cave in to dip into Fighter on my Vivi. So many good feats, so little slots. That'd at least give me martial for free + another combat feat earlier. Might also take a second one later, if I feel like delaying the progression even further makes sense (probably not). But I'd loose True Mutagen (2 armor, 2 Dex, 4 Con) plus bonus Discovery, caster levels and additional level 6 extracts... at level 20 though, I'm not sure I'm gonna even reach. So maybe better to reap benefits early.
I don't even have space to properly invest in max Preserve Organs!
1 Power Attack
2 (Discovery) Cleave
3 Finishing Cleave
4 (Discovery) Combat Expertise -> That's where I'm now, in Stag Lord's Fort, almost level 5.
5 Trip
6 (Discovery) Feral Mutagen
7 Free feats: Martial Proficiency, Armor Medium, Heavy, Feat: Outflank, Fighter Bonus: Tandem Trip => Vivi betrayal? But I could really use those 2 bonus feats ASAP.
8
9 (Discovery) Preserve Organs, Greater Trip
10
11 (Discovery) Crippling Strike, Fury's Fall
12
13 (Discovery) Greater Mutagen, Blindfight
14
15 (Discovery) Mummification, Combat Reflexes
16
17 (Discovery) Grand Mutagen, Seize the moment
18
19 (Discovery) Dispelling Strike, Wings
20 Largely open. Fighter bonus? Toughness? Dodge? Maybe Rogue? Or just finish 19 Vivi for another k6 sneak and extra lvl6 spell I guess.
Of course should have picked Feral Mutagen sooner. But it should still come in handy. Particularly the free Bite, particularly if it combo's well with the Cloak of the Winter Wolf. Already have the Amulet of Mighty Fists for it
Edit: Damn, forgot Outflank. Need to squeeze it somehow in there as well!
