This mini-mod turns some base-game item combos that aren't synergies into actual proper synergies.
This is done mostly so the synergies can be documented by Item Tips Mod and so they can be completed by Synergrace or Synergy Chests

So far it makes 2 item combos into proper synergies:

• The Ring of Mimic Friendship and Mimic Tooth Necklace combo that makes it so all chests are open.
• The Elder Blank and Full Metal Jacket combo that makes it so upon taking damage, if Elder Blank is charged it will be used automatically instead of a normal blank.

If there are any other item combos in the base game that should be made into synergies let me know.
I also include an optional file for Item Tips Mod that includes the descriptions for those synergies.

Special thanks to SpecialAPI for his synergy code.
