Human rogue weapon master with grenadelikes, need help building it

[Epik]

Need some guidance, can't really figure out how to stat something like this.

Access to flashbangs is usually considered a sort of capstone feature for rogues, and it doesn't happen until level 24. If using grenades is your thing, I wouldn't recommend going less than 24 rogue levels.

You're also dealing with the problem of needing all those feats to be a weapon master, and this isn't even a human build so you're going to struggle.

You could do what you're trying to do and it would probably be playable, but I wouldn't recommend it.

I would recommend 25 rogue 5 fighter. You could replace fighter with ranger (an extra feat in epics), indivisible blade (fun toys) or blackguard (more sneak attack dice, charisma to saves). 5 Divine champion wouldn't be bad either and 6 harbinger is fun. But deep rogue builds, especially grenade focused ones, really want 24-25 levels in rogue.

If you want to do something extremely unconventional with less quality of life but optimized grenades, you could even go 30 rogue and pick up gruesome technique for maximized grenade DCs and a chance of fear effects going off when you throw certain grenades. I wouldn't recommend this as you trade a lot of combat power for grenade strength, but it sounds fun.

In my opinion the idea you proposed is a little questionable.

Alright... Well, since my friend recently called off the idea due to being a little too busy to keep up a little clan of troglodytes, how would it go as a human, then? Might aswell use the idea still since I've been wanting to make a rogue weaponmaster for a while now, because I haven't actually used rogue at all and also haven't used grenadelikes at all. Just seems like a new fun thing to try out, like I said, just having trouble figuring out how to stat such a build.

Human alleviates the feat starvation a little bit, but the general idea still stands that being a serious grenade user requires 24 levels of rogue. I would say you pick one or the other: Do you want to be really good with grenades or do you want significant levels in weapon master?

If you want to do the deep rogue grenade thrower thing I can advise you pretty well. If you're looking for weapon master builds with rogue levels I don't have a lot of expertise in the matter. Although a friend of mine did have fun as a human weapon master 7 rogue 13 cavalier 10. This build does good damage for a dex character, especially when sneak attacking. It takes full advantage of the cavalier class, has significant goodies from WM 7 and gets epic dodge from being a rogue. It does not make use of grenades, and I can't advise super reliably on what feats to take.

As for ability scores I would do something like this whichever route you take:

Dex 17 (19)
STR 13
Con 14 (16)
Int 14
Wis 8
Cha 8

You could choose to lower STR to 12 and WIS to 9 if you want, so that two uses of owls wisdom (+5) would raise your will save by +2. Having 13 STR is useful though as it improves carrying capacity and lowers your strength gearing burden.

If you go the grenade user route, there is an argument to be made for flattening STR to 10 and starting with a dex of 18 (20). This is a bit frustrating because your carrying capacity will suffer and you'll be locked in to taking great dexterity in epics to attain an even number. But your end game DEX will be optimized and this your grenade DCs will be slightly higher. 20 DEX at level 1 is not an absolute necessity however, it just makes your grenades slightly better at the cost of your secondary ability scores and feat economy.

Alright, thanks for the tips and what not, I'll probably test the wm option and the bg option in PGCC
