Yes but Spear is a buff on your character so it makes sense that it works the same as Cleric. The thing with Stratagem is that it's a debuff on the boss which makes me believe that during those 15 seconds any damage on the enemy be it a DoT tick or a Skill/Spell will be affected by it.

This is just theory though as I haven't tested it but i do believe it works this way

If that's the case then the opener should be Cleric -> Ruin II -> Stratagem -> DoTs yet I haven't seen ppl doing that in speedrun videos.
