Use a cleaning application like clean master to clean junk from your device, then move as much applications to sd-card to alleviate device storage (clean master does that too).
If you're rooted try removing system applications that you are no using

Can you fully remove Google system apps from Android including the Play Store updates?

'Insufficient space on the device'
So far, the tree seems rather underwhelming, especially the low-tier skills like Myelin, More Pep, Strength of 5 gorillas, etc.

Evil Enchantress apparently doesn't affect shock, fire and acid direct damage; it only buffs the status effects which is pretty pointless when slagging an enemy does 3X damage.

Shock storm doesn't sound useful as most enemies won't be bunched up enough.

On the other hand, the damage buffs from Wires Don't Talk and Interspersed Outburst look very useful. Make it Sparkle also apparently gives Deathtrap massive additional damage of up to 3X.

Is it worthwhile to spec into this tree just for the end-tier perks?
