Yeah, I reduced the cooldown from Talisman to 90 seconds tho. I had the feeling it would become a popular pickup. This is also on of the reason I made the buildpatch similar to Mikael's Crucible so that only of part of the recipe contains combat stats. To look to to after all this. I happy with the result & in theory the Royal Sole/Royal Sunlight/Royal Sun/Rising Sun (dam really need to define that name) would be the armor alternative for sustain supports to go for. If the item still feels to strong that armor or active cooldown can still be hit.

I kept the 60 seconds cooldown from Arctic Mageblade for now. The total price & the lack on defensive stats would make the item pretty situational. So shorter cooldown on the active wouldn't make the item that overpowered. If it later still becomes a problem, their is always the nerf button.
