Make an Item!

[NTN]

Life Vest

The Pokémon floats after getting hit by a Water-type attack.

(Like Air Balloon that only takes effect after a Water-type attack, only it doesn't pop)


Clown Nose

Adds a 10% chance of confusing the foe to attacks.


Surfboard

The holder's Water-type attacks will always strike first.


Gas Mask

The holder cannot be poisoned.


Hazmat Suit

Prevents status effects.


Chew Toy

Absorbs the foe's bite attacks.


Binoculars

When the foe tries to lower the holder's accuracy, it gets increased instead.


Rubber Duck

Activates Substitute when the holder is hit by a Water-type attack.


Fire Extinguisher

May leave the foe's Fire-type attack with no PP after the foe uses it.


Magic Broom

The holder may stay in the sky after hitting the foe with Fly.


Bubble Wrap

Halves damage from physical moves.

Alarm Clock- If the Pokemon is asleep, it will instantly wake up in between turns. Special property of this Hold item is you can only use it in 10 battles (including Wild encounters) and need to reset it after 10 battles, you must unequip it and put it in your bag and walk for 500 steps before it can be used again.

[Wolstenholme]

Toy Soldier
Increases the user's attack stat, but cuts accuracy.

[SirBlaziken]

[the bread dragon]

Guitar

All sound based moves' base power in increased by 1.3x.

Ice Cubes

Increases Ice-type moves by 1.3x. When the weather is sunny, the ice melts and the boost is lost.

[NTN]

Slingshot

Moves that strike more than once may last twice as long as they usually do.
(Bullet Seed 2-5 becomes Bullet Seed 2-10)

[the bread dragon]

Snow Globe

Hail lasts longer (9-14 turns) and ice type moves are powered up by 1.3x when held.

[SirBlaziken]

Special Medicine

All moves that heal hp (damage dealing and non-damage dealing) heal the user slightly more.

[Captain Jigglypuff]

^That. Would. Be. Awesome! I've always wanted the Secret Medicine you got in GSC/HGSS and DPPt to be useable!

[SirBlaziken]

Thanks! I hadn't even thought of the item to be like the secret medicine in DPPt and GSC/HGSS.

Black Mask- Pokémon that are the Dark type have their attack stat doubled, but their accuracy falls by one. The mask cracks and breaks if it is hit with a physical attack over 80 power.

Gameboy- Foe may become confused or paralyzed if they hit the holder with a physical attack.

Mareep Wool- Halves damage taken from attacks, but sharply lowers speed.

That's all I got.

[SirBlaziken]

Basket- Allows the holder to hold two other items. Cannot hold two elemental plates or two of the same item.

[MonsterMon64]

Rubber Suit
An amazingly stretchy suit that stops Electric-type attacks, but Attack and Sp.ATK fall with each hit.

I can picture this being fun in Doubles, somehow. Give it to something with Contrary, maybe? Only other thing I can think of is slapping it on a Gyarados with Moxie, but not sure if that'd even work out well. Probably would work better on something defensive in most cases, anyway. Mantine?

[SirBlaziken]

Bird Cage

Opposing pokemon cannot switch out while the holder is in battle. Ghosts cannot switch out.
