How Physically Strong is the Warrior of Light?

[Dikatis]

I'd generally put forward that Estinien is stronger in a 'brute strength' way, it's just that the WoL is a better fighter.

Which is exactly something that'd come into play in a duel against Gulool Ja Ja. You don't destroy the royal palace you're a guest in, that's just rude.

Well, remember Gulool Ja Ja's challenge to the Warrior of Light.

The battle rage is upon me! I'll stop short of killing you, of course... but expect no other mercies!

Gulool Ja Ja and the Warrior of Light were going full throttle. Their pride as fighters wouldn't let them do anything less. And Gulool Ja Ja claims that WoL is the first one to withstand his full strength.

I've brought my full strength to bear against opponents before, but you are the first to withstand it. Even with my Head of Reason asleep, I never expected you to give me so much trouble... Estinien did not exaggerate: you are a force to be reckoned with!

Gulool Ja Ja would WANT Estinien to use his full strength and Estinien would almost certainly give it to him given his interest in worthy opponents every now and then.
