With tinker you can rearm manta. If you use 2 different manta (after refresh) you'll have 4 illusions.
Theorically you can have 18 tinker on the map with 6 mantas, one illu rune @ '59, one illu rune @ '01, and one illu from your friend morph. Actually, that's my secret dream. I know one day i'll have them all.
