The power cores are stacked vertical with my crafting unit. (Correction) I feel silly 
. I have 24 coils. I forgot a couple were buried and I couldn’t see them. Coils fixed.
Compass: I only tested this skill hunting, not in cities. The description says Nearby Creatures. So adding Widescreen increases that range 75%. This leads me to believe it’s mainly for hunting not player finding. So Using it in the wilderness is when I noticed that mobs don’t spawn 75% further out where the Widescreen skill would see them. They spawn within the radius of the tier 1 compass skill. Like when Meteor hunting, the mobs do not drop until you get into the meteors range. Having the Widescreen skill does not make the mobs spawn from further away. Thus making the widescreen kinda obsolete.
I meant Health Regeneration in the Endurance tree. Intelligence increases the Healing Potency, so should increase the % of all things that heal, like being Full(health regen), or choosing the Health Regeneration skills, as well as the Healing Bombs. Or change the description of the Intelligence skill to exclude these other health bonuses outside of Sapphire bombs and Healing Brews.
