Riddle of Earth (Lv. 64, Melee DPS): Grants 3 stacks of Riddle of Earth, each stack reducing damage taken by 20%. Duration: 10s/Recast: 30s. Maximum Charges: 3.
Arcane Crest (Lv. 30, Melee DPS): Grants Crest of Time Borrowed to self, creating a barrier that nullifies damage totaling up to 10% of maximum HP. Gradually restores HP (50 potency/tick for 15 s) to self and nearby party members when barrier completely absorbed. Duration: 5s/Recast: 30s.
Third Eye (Lv. 6, Melee DPS): Reduces the amount of damage taken by the next attack by 10%. Increases Kenki Gauge by 10 when hit. Duration: 4s/Recast: 15s.

Oblation (Lv. 82): Reduces damage taken by a party member or self by 10%. Duration: 10s/Recast: 60s Maximum Charges: 2.

I understand that you have to take mitigation actions in the context of the larger toolkit, but this is why Oblation is underwhelming. If it's meant to just be a TBN upgrade, make it a TBN upgrade. Otherwise, at least let it outshine a Lv. 6 melee dps ability.
