If the triggered ability resolves while Daxos’s Torment is already a creature, that ability will override any effects that set its power or toughness to a specific value. Effects that modify power or toughness without directly setting them to a specific value will continue to apply.

Although Daxos’s Torment will become a creature after it enters the battlefield, it doesn’t enter as a creature. Abilities that trigger whenever a creature enters the battlefield won’t trigger.
