Greatly increased
The first one is the ability "Invisibility."
After reaching level two, not only does the invisibility duration extend to one hour, but he can also conceal the heat he emits. Even specialized instruments cannot sense his presence.
The second one is the ability "Fire Control."
There's been a significant transformation in Fire Control. This time, Waldo can manipulate even more formidable flames, and the flames' power has greatly increased. They give off a chilling sensation, but the temperature within is even more terrifying.
Second-level zombies have no resistance and are instantly incinerated. Third-level zombies can hold on for a bit, but they too will perish in the flames before long.
