what does the bacpack do ?
* Heroes now have a backpack that provides 3 extra inventory slots to carry items around with you. Items in those slots are not active and do not grant any bonuses. Backpack items can be used to complete recipes. You can swap items from and to your inventory.
Rules:
- Items that are in your backpack are Inactive (cannot activate nor benefit from passive bonuses)
- Items that are moved out of your backpack remain Inactive for 6 more seconds.
- Item cooldown at only half the rate when they are anywhere except your main inventory
- Cannot put the following items in your backpack: Gem, Rapier, Bloodstone and Aegis.
- Items can always be moved out of backpack with no Inactivity timer when near a shop
* Disassembling items now tries to fill your inventory or backpack first before dropping to the ground
* Disassembling items auto-locks them from combining with other items. Use right click to unlock.
basically you can carry 8 item, but 3 item wont have effect on you actively or passively. I guest this will be buff more to suports as they can easily change consumable support items ( low cds) rather than to core juggling refresher manta bkb etc (they still can but that reduce refresh time will hurt it)
