Actually the bigger problem was nailing the hand on the wall. With the help of multiple natural language prompts to help, it just can't get it right. Yeah, it's too niche even for guro standards.
Using 'crucifixion' tag might have make it a bit easier, but then I had to remove the cross, which is near impossible.
So, I just had to keep rolling the gacha until I hit the jackpot. But even when I get the nails right, the text might be wrong pretty often.
