Make an Item!

[Spriter]

Majestic Antlers

These elegant antlers boost the attack of certain Pokémon (Deerling / Sawsbuck / Stantler) by two stages, but reduce the defense stats by 1 stage.

[SirBlaziken]

Masquerade Mask

Raises both defenses by 1, but lowers both attacks by 1.


Power Launcher

Raises both attacks by 1, but lowers both defenses by 1.

[Spriter]

Yeah because Xerneas and Virizion totally need an item specific to them...

Magic Rune

When the user drops below 50% HP, this has a 30% chance of increasing Special Attack by 3 stages.

[SirBlaziken]

^I call the other one.

Power Word

When the holder's health drops below 50%, this is a 30% chance of raising the holder's attack by 3 stages.

[Spriter]

The rune thing was more of a reference, dunno if that would be the counterpart.

Seriously though, Sawsbuck and Stantler need way more help than Virizion.

[SirBlaziken]

Stopwatch

The holder gains +1 speed at the end of each turn. Same rules as speed boost.

[Jampie]

Sharp Tooth

Increases your physical attack by 1.5x if your health is below half.

Now there could be a giant competitive use for this item if made.


Say Azurmarill came out and holding this item then used belly drum and got to half this would make Azurmarill incredibly strong or any Poke'mon that knew belly drum honestly.

Syringe

Increases the chance of a move's added effect by 10%

[SirBlaziken]

Chakra

Any attacking move that is used from a distance hits twice, any move that already hits more than once can hit twice as many times.

Normal Move: 2 times
Repeating move (like bullet seed): 2-10 times

[Gusparce]

Golden Leek

If held by Farfetch'd, increases critical hit chance is increased to 50%.

Something to make him more useful? But not really. 

[Dorchadas]

Holy Monocle

Adds 50% power to moves that hit more than one pokémon, but they now only hit one target. Only works in double/triple battles.

[Mockery for One]

This one's called the Arceus Amulet, and maximizes all stats, but causes confusion. It acts as a shout-out to the Alicorn Amulet form Magic Duel.

Now here's one called the Plenty Repel, and it lasts as long as your current session. It's useful if you want to just tour the region, and have an entire team of Lv. 100s, or want to hatch some eggs.

[Spriter]

Speaking of repels...

[type] Repel - repels the Pokemon type specified in the name, e.g. Water-type Repel

[Mockery for One]

The Pixie Rod increases the power of Fairy Type moves.

The Glowing Spark increases the power of Light Type moves.

The Luminous Plate does the same, but this time it allows Arceus to become Light Type.

[Dorchadas]

Air Cloak

Doubles the power of all flying type moves, but each turn you take 25% damage.
