I wish this thread owner was around to update etc.
What we have been playing with (50h rares and 65h non-rares) I think should be the hit limit for Sandbox TA.
Other rules:
Max of 100 in a single attribute.
Only be able to use items obtainable from the normal mode. (No sonic team armor)
Proper weapon percents on weapons with KC.
You can only change Non-rare/S-rank special attacks. (No type weapons with charge/zerk)
Cannot make items mid run i guess is another one. lol
Can't really pass the original post privilege to someone who isn't a moderator, so closing this thread so you guys can make another one. Feel free to link to this thread from the previous if there is something you wish to reference in it.
