I'll put the information I have here, instead of on the vendor page.
Respawn:
The SoEE will respawn each time you revive and die again (die while in body-form), in any world or nexus.
- Tried after reviving as a blue (several times, in different worlds), +1 each time.
- Turned World 2 Pure Black with revival/suicide after consuming soee's, and went to 5-2 and bought a new one after each death.
- Killed Dragon God and suicided, one more soee available.
- Have not tried to get body back after invading, since I'm going for pwct first.
Price:
SL 4: 1.000
SL 18, 20: 3.000
SL 30: 5.000
SL 32: 10.000
SL 44: 15.000
SL 53: 20.000
I don't know the exact SL numbers for the price to change.
