Eve of the Apocalypse: Twilight

Curious if anyone uses these, or alternatively to have a discussion about possible ways to use them.

I'm not sure most people realize but these got changed recently, so that you'll never loose a stat only the crystal invested. Note that there is also a 100% success rate when converting from a higher to a lower stat. It becomes more risky the more imbalanced the stats are (ie 10 str 20 agi, doing str->agi will take a bunch of attempts).

I've never used them. I would rather invest my crystal in something that's more reliable, like talents.

Is it global like the stat upgrades?
