Build transition help (ele weakness)

Selling rn is tricky. I would recommend checking out iamjustanthony and his multitude of bm coc builds. He has several budget tiers as well and his deodres ew only requires 138 spirit. I'd say you will want a different amulet with +3 spell skills and probably spirit. Atziris acuity gloves are also very good for that build. You should also check some ninja deodres ew builds that use wand for reference, but I'm pretty sure they're fairly pricey. You also want as much es on your chest as possible.

If you stick with wand, pretyy sure you'll want the rathpit focus. Looks like most of your gear should work, but you will likely need some adjustments. Yes, you will likely want to change your tree to get some curse points. You want that low activation time and radius of at least 4.7m for best results. This build also requires high crit chance, so you either get it from tree or jewels, so probably new jewels.

Here is my current deodres ew for reference, if you're interested. I run 100% cc.
