Hi everyone,
not sure if it's intended to work like that, but I doubt it.
You can use Symbiosys on your team mates, they use their new gained spell and you switch it to your other mate.
Works espescially good with Druid / Shaman / X.
So to sum it up (just an example, has more potential)
Step 1: Use Symbiosys on shaman
Step 2: Shaman stelths
Step 3: Cancel Symbiosys and give it to other mate to gain a real useful spell (Dispersion from Shadow)
Step 4: Shaman still is in stealth
Step 5: ???
Step 6: Profit
