Dormant Power

Passive:

Defense - Natural Armour (start with natural armour bars and toughness) and Lockdown (immune to all damage for a couple seconds) however, using Lockdown gives slowness throughout and slightly afterwards.

Gale - Friendly Breeze (slightly faster movement and no fall damage) and Dash (momentum-based horizontal dash with slight upwards boost) but with less attack damage.

Growth - Photosynthesis (saturation in sunlight) and Rapid Sprout (free bone meal ability) but weakness while under cover.

Nyx - Darkvision (unlimited night vision) and Vanish (invisibility, smokescreen and slight dash). Dequips all armour when Vanish is used.

Tidal - Ocean's Current (permanent dolpin's grace and conduit power) and Riptide (free riptide effect, between level 1 and 2 enchant). Tidal users have no real weaknesses, but they still take fall damage, so must clutch if Riptide is used wrong, which is easy to do.

Warp - Reflexive Dodge (3% chance to 'dodge' a damage tick) and Teleport (48 block range teleport). Teleportation leaves you sick after use and gives slowness, weakness and mining fatigue for a few seconds.

Active:

Arachnid - Weaver (free cobwebs) and Poison blast (create a poison explosion around you), but less natural HP.

Burn - Fireproof (unlimited fire resistance) and Fireball (shoot 3 blaze fireballs, and then a ghast fireball). Unfortunately, you have slower attack speed.

Frost - Cold Immunity (cannot take powder snow damage) and Frost Blast (freeze an enemy you're looking at and slow them down). No real weaknesses due to situationality of powers, though the slow can be rather useful.

Quake - Stalagmite Step (no damage from falling on stalagmites, yes this means clutching with them) and Earth Strike (deal a burst of massive damage to target entity, followed by evoker fang). Since they have the most offensively powerful ability, Quake users as a result get weakness while in the air, making critical hits near useless.

Sanguine - Regeneration (free regeneration 1) and Sanguine Shot (fire a blood projectile), though naturally, the blood projectile costs HP to use.

Thunder - Conductivity (getting struck by lightning gives buffs) and Thunder Blast (strike lightning at target, which could be yourself). Using your Thunder Blast ability gives weakness and mining fatigue for a bit.

Talismans:

Talismans are the way you get powers. Crafting recipes in the gallery. Talismans, once right clicked, will grant you the corresponding power, and will also refill your ability cooldowns. They can therefore be used as batteries of sorts. They can be ver useful for Quake or Defense, which are abilities that have long cooldowns. However, they only have 4 charges, so be careful!

No refunds, of course.
