I am trying to run an Isekai campaign, and I want an advantage that works like the "item box" or "inventory" that is so popular in those stories.
Browsing the "powers" rulebook, I've found under Snatcher:
For storage only, buy Payload with the Cosmic modifier.
The payload advantage gives you 10%/lv of your light load as storage for 1pt/lv, the cosmic modifier allows it to go into a subspace for +50%;
So the advantage looks like this:
Item Box 1.5pt / level (Payload 1/lv + Cosmic +50%)
Allows one to store items weighing up to 10% of the character's Light Load per level of the advantage, in a subspace. Items can only be stored or retrieved by the character.
Now I would like to slap a modifier on that advantage so time does not pass for items inside the storage. How much % should be this timeless modifier?
By the comments, the setting is a high fantasy medieval swords & spell. TL is middle ages. Available spells for starting players are only those in the 4th ed Basic Set.
