Ninja: Walk in shadow.

[MartaDemireux]

They're gonna need some way to manage TP. Either Invigorate or some other source of damage to weave in with reduced or no TP cost. Right now the only TP-based classes that don't have Invigorate are the tanks, who both have alternate ways to manage TP.

Well if the datamined traits are anything to go by they have an inherently higher TP regeneration.

Roughly translated for people (they are traits):

ＤＥＸアップ (Lv8) - DEX up.
-> ＤＥＸを2上昇する - Increases DEX by 2.

落下ダメージ軽減 (Lv14) - Fall damage reduction.
-> 落下による被ダメージを軽減する - Reduces the damage caused by falling.

ＤＥＸアップII (Lv16) - DEX up II.
-> ＤＥＸを4上昇する - Increases DEX by 4.

ステルス効果アップ (LV20) - Stealth effect up.
-> ステルス中の移動速度低下を軽減する - Reduces the movement speed reduction when in stealth.

ＤＥＸアップIII (Lv24) - DEX up III.
-> ＤＥＸを6上昇する - Increases DEX by 6.

移動速度アップ (Lv28) - Movement speed up.
-> 自身の移動速度を上昇させる - Increases personal movement speed.

単体特化毒Buff効果アップ (Lv32)- Single specialized poison buff effect up.
-> 単体特化毒Buff（猛毒）の与ダメージ上昇効果を20％に上昇する - Single specialized poison buff (Highly Toxic) increases physical damage by 20%.

TPリジェネ付与効果アップ (Lv36)- TP Regen effect up.
-> TPリジェネ付与によるＴＰ回復効果の効果量を上昇する。 - Grants increased effective recovery amount of TP regen.

複数特化毒Buff効果アップ (Lv40) - Multiple specialized poison Buff effect up.
-> 複数特化毒Buffの与物理ダメージ上昇効果を10％に上昇する - Multiple specialized poison buff increases physical damage by 10%.

コンボB-1効果アップ (Lv44) - Combo B-1 effect up
-> コンボB-1の継続ダメージの威力を45に上昇する - Combo B-1 DoT increased to 45.

ナイフ投げPBAE効果アップ (Lv48) - Knife throwing PBAE (Player-based Area of Effect?) effect up.
-> ナイフ投げPBAEの威力を80に上昇する - Knife Throw PBAE power rises to 80.

They obviously could change any of the traits as they're in development but as of now it's all we have to go on.
