[Chase 94]

I'll bite. First I'll start with some story given "passives"..they shouldn't be too excessive buffs, and they leave your item slot empty. Ideally, the largest effect these passives should visibly have is on PP of moves.

Dodge Ribbon - slightly boosts evasion - earned after beating 1st Gym leader

Continue Ribbon - slightly boosts PP of a selected move by 1 - earned after beating the 2nd Gym leader

Nullify Ribbon - slightly boosts the chance moves fail to affect the holder - earned after beating the 3rd Gym leader

Full Ribbon - slightly boosts user's HP - earned after beating the 4th gym leader

Fortify Ribbon - slightly boosts user's Defense -and- Special Defense - earned after beating the 5th gym leader

Armed Ribbon - slightly boosts user's Attack -and- Special Attack - earned after beating the 6th gym leader

Dash Ribbon - slightly boosts user's Speed - earned after beating the 7th gym leader

Reload Ribbon - slightly boosts the PP of all moves a user has by 1 - earned after beating the 8th gym leader

Intimidation Ribbon - slightly increases the chance of flinching moves to flinch the target - earned after becoming the Pokemon League Champion.

[Damage 13]

Randomizer- At the start of battle one stat is raised 3 stages while one stat is lowered a stage. In the case of HP it is raised 30 points or lowered 10.

Gigas Rings- The pokemon receives the slow start ability but after the five turns atk, sp.atk and speed are doubled. (No effect on Legendary Mineral pokemon)

Edit: I like the Ribbon Idea and the Nullify Ribbon would be awesome but lowering accuracy of I assume status moves that early would be a little too advantageous.

[Chase 94]

I tried to go out of my way to insinuate that these would be passives and would not be very noticeable. The effects should feel more like spurts of luck than a regular occurrence.

[Vinny 27]

Support Vest: Protects the user against all non-volatile status conditions, confusion and stats lowering moves.

Prevents user from using Status moves.

[Damage 13]

Re read it and yeah I gotcha.
