Arena: The Heir of Yggdrasil
Field Type: Grass
Complexity: Intense
Format: Maximum 6v6 Triples
Summary: Where the Trilithon Array is merely shaped like a tree, the tower known as The Heir of Yggdrasil really is a tree, or rather several trees; a gigantic stand of ashes and yews looming out over the little town of Gamla Uppsala in Sweden. Not only is it home to several rare species of European woodland life, it's also a haven for Grass-types, who brave the cold to come and pay homage to the Original One. At the top is a fortified arena - in fact, it's the second-largest of them all, and its interior resembles an earthly paradise, created by Arceus to aid the Grass-types and maintained by the Grass-types to honour Arceus.
- All Pokémon on the field gain the effects of the Meadow Plate.
- There is grass, water (both open and in the form of a small waterfall), and sand; however, the only rocks are artfully-placed pebbles. Moves that require open sources of rocks have their BAP reduced by 4, but may hit all enemies if they do not do so already.
- The arena is enclosed;, but hugely spacious; weather is unable to affect the battle.
- Camouflage changes the user's type to Grass-type.
- Nature Power changes to Seed Flare, but does 25% recoil damage.
- Grassy Terrain and Rototiller are both constantly in effect.
- Play Nice becomes a 4 BAP damaging physical contact move with a randomly-selected type from the following list: Grass, Water, Ground, Flying, Fairy, Fighting. Its effect remains unchanged.
- Pokemon under the effects of Ingrain regain 6 HP per action and reduce the BAP of incoming special attacks by 2.
- Chlorophyll, Solar Power, and Overgrow are constantly active; Pokemon with one or more of these abilites gains the additional ability Leaf Guard. If that Pokemon already possesses the ability Leaf Guard, then every time they are hit with a move that inflicts a secondary Status effect (e.g. the burn chance from Flamethrower triggering), they heal 3 HP.
- Pokemon with Sap Sipper have their evasiveness lowered by one stage, but heal 4 HP per round.
- Hyper Beam is Grass-Type and inflicts the effect of a randomly-selected powder move (this still affects Grass-types and overrides the effects of Overcoat); Normal-type Pokémon still get STAB if they use it.
- Frenzy Plant does not incur a turn of Sluggishness.
- Worry Seed, in addition to its other effects, increases the target's evasiveness by one stage but giving all their moves a 30% chance to inflict 25% recoil damage. This is affected by Serene Grace.
- Sawsbuck gains +1 base Attack rank and does not receive recoil damage from Normal-type moves.
