I read everywhere that razortail is THE belt for java.
My question is, do i have to wear it, if i already skilled pierce on java?
Or only if i want so save some points?

For PvM you want 100% pierce, you get 33 from razortail and skill pierce until you get 67%+ from the skill itself.

You would like it for pvp as well, as gm people got oaks/golem and other summons.
And the bm ones uses merc.

If ur java got and descent ammount of psy dmg zoo's and merc falls to 1 fury if 100% pierce meanwhile the enemy player gets dmg and stun.

It might take your fury from 80% to 100% pierce. Which is good, but not necessarily critical. It only applies to the primary javelin projectile, not the released bolts, as those are autopierce by default. So if you throw a javelin into a 20 monster mob on a path that hits 4 monsters, 100% pierce will hit 4 and release 80 bolts. 80% pierce would hit on average ~2.95 monsters and release on average ~59 bolts

razortail in pvp should be the new frontier along with throwbarb.
We're ready for 1.15 now

We use bugbelt on eu for that pierce. It's a combi of razortail + nosefertu's coil with some plesant adds^^ However i agree that razortail's aint worth it, but the skilling of pierce is crucial

Going from 80% to 100% pierce in pvp is mostly irrelevant. Sm/golem are just 1 unit that can move out of the way or be dead, while dudu stack explodes in 1 fury
that extra 80->100 pierce is good in pvm when you throw into mobs of 20-30 monsters with high hp, but in pvp its nothing

yeah, being eu i heard about that belt sometimes

Does the % chance to pierce go down with each monster is goes through or it stays the same throughout? For example, if I had 100% pierce and threw a java threw a row of infinite monsters, would it pierce through all of them?
