Got the two outstanding achievements. One is for beating a boss after the tutorial without incurring damage. The easiest candidate is the giant undead vicar who shoots glass shards from his hands.
The other achievement is meant for replays, where you need to sequence-break and enter a mid-game area in only the first thirty minutes of play. Never got the equivalent trophies in the first game, as they were far more strict.
Five dummy achievements were added for a future DLC or update that's likely to advertise Blasphemous 3. Will probably find the second game a hard act to top.
