You can mix since this is just a temporary weapon until you get your 315 orange and maybe a stats reset. We can also expect a str rework soon so nothing to be worried.
Consider the following:
3x Lv 6 yellow gems = 1080 CA, 1620 on a highlander.
This is by far the best option on a full dex character.
But since you went with 50 base str, you could mix in a Lv 6 green gem to help a bit. STR is not useless:
50 points = 115 STR after the R8 bonus, which translates into 149 ATTACK from the swordsman x1,3 bonus AND 115 critical attack (165 since he’s a highlander).
So if I’m not mistaken this is 223 attack + 165 critical attack when a crit occurs = 388 damage before reductions attributes and etc, not even considering dov or moles (that boosts your extra p.atk).
388 attack. So what if we one green gem into this instead of 3 yellows?
Lv 6 green gem = +38 critical rate.
2x Lv 6 yellow = 1080 CA + 388 attack. (let’s consider it a 1468 total without dov/moles).
HL attribute really favors yellow on almost any scenario but this can make up for your critical rate for now I think and the damage loss is not that impressive for a temporary weapon. I know that 50 invested dex turns out to be 75 critical rate in the end (the more you have, higher the bonus…) but I think it can work. Unlike fencers, when DoV is up, you still deal good damage even when you don’t crit.
Calling @Lostac and @Kascly to check my numbers since I might be missing something.
It’s interesting because my fencer has 50 str (block pen is too important for me) invested too and I’m thinking on upgrading my venier from 2x lv 5 green gem to 1x lv 7 green + 1x lv 7 yellows (and we don’t have hl attribute on rapiers so it’s a more okay change I guess) …
