5 battle item slots and Artifacts (non-consumable battle items)

Yes I realllly think that there should be 5 slots for several reasons.
-SG may be reluctant to do so since people tend to bring lots of attack items to bosses and ‘nuke’ them; 5 of each arrow/axe/bomb/dragon attack do a total of 5000 damage to all enemies on a board.
-This can be solved without having to rethink/rebalance all boss battles by making the limit for each of those four specific attack items change from 5 to 4, and then adding a new attack item that does 250 damage to all
so if someone brings in all attack items they still can do 5k damage total (note this does not consider the 132 dot damage of the dragon attack over 6 turns each. Also the harpoon and caltrops from the hunters lodge are not considered as well since they only hit a single target and are costly to build)
