New Inspiration Keystone
Bargain Bazaar
All non-consumable items in shop are 30% cheaper, but are also 30% weaker.
By weaker, I mean that item stats will have their numbers reduced by 30%, but actives and passives will not be touched or changed.
I.e
will have 28 AD, 17.5% attack speed and 8.4% lifesteal, but cost 2240.
I admit, that this isn't a very balanced idea, and suggest it more as a thought experiment then anything else.
