How To Build Pele Correctly

I overall prefer to just use the core build all the time, if youre playing smart then it doesn't make too big of a difference, sometimes I sub in some defense. As for the abilities you need to at least get Pyroclast to level one early game, you miss out on tons of damage/kills without the range. I swapped Pyroclast to level 1 at level 4 and put Magma Rush's last level as level 14.

Whether or not Pyroclast is a good damage skill in your mind, not even having it as an option for ranged damage until level 14 is crazy talk. Your skill leveling order is whack.

With a couple basics weaved in (with the additional damage assistance from Hydra's Lament, 440 (+120% scaling) at max rank of Pyroclast is nothing to scoff at, and as the levels go up, the additional return damage it can provide (such as on objectives where you can make sure you get all the return hits) provides an additional 100 +75% damage.

Pyro, again with weaving basics, will also give you better burst and can help stack those Stone Cutting Sword protection reduction stacks, if you're sure of that item choice. If you DON'T use Pyro that way, you're going to get much less use out of SCS, because she's really more of an ability user rather than a basic attacker.

Masamune is an interesting choice in the "damage team" build, but I think you'd be better served with an item with some pen in it in the 3rd position. As a jungler, she'll want the added damage from pen, and she's got plenty of MS in Magma that she shouldn't need the MS from Masa that much.

The concept of your build against a tanky team is okay, as you do build a lot of pen/protection reduction...but I don't think you realize how that works. Specifically, protection reductions are calculated before penetration. The fact that you add Titan's Bane specifically to that mix means that you're getting reduced function/efficiency from the item.

Let's say you have an enemy with 200 protections. In your build, you have 15 flat pen, up to 50 protection reduction, and 15-40% penetration.

In just calculating Titan's Bane by itself, you'd get 40% pen when facing 200 protections. You'd thus reduce protections to 120...you're getting the equivalent of 80 pen.

Throw SCS and Void into the mix, and at full SCS stacks, you're dealing with 150 protections. Now, TB will have reduced effect, because it scales to a max 40% at 200 protections. At 150, you're getting somewhere in the range of, I dunno, 32%? 32% of 150 is 48 protections. 48 protections vs 80 is a pretty significant drop. Sure, you'll still get better overall pen with everything together, but that's a lot of inefficiency, and you've sacrificed getting some other useful items in that build to get that level of pen. Not suggested.
