The beauty of old SCH arsenal of DoTs was it was impossible to apply all of them perfectly. The 5 DoTs that I recall are:
- Bio I (18s)
- Bio II (30s)
- Miasma I (24s)
- Crossed Aero I (18s)
- Shadowflare (30s) - costing an Aetherflow & conflicts with Sacred Soil.

All have differing timing. All has to be cast under Cleric Stance. All has to be done within the constraint of 2.50s filler cast time. SCH’s DoT can also be spread at the cost of yet another an Aetherflow. There was also Miasma II that can be used as mobility tool + AoE gain but taxes their MP. Then there’s quickened aetherflow…

Oh joy…
