I wanted to talk about my Albus here because even at level 30 I'm still using the base of this build because it's so damn good and covers his essentials.

For 5 TP this synergy is insane. 20% Block at a baseline, 5% per enemy in LoS, and another 20% if enemies > allies in LoS. It's a huge amount of Block even if the last effect isn't active, but it pretty much always will be in the early-game. This synergy makes it trivially easy to hit 100% Block even if you have displayed 60% and 100% Block lets you take punishment indefinitely. I think you have a few more points to play with but I can't remember what else I was using, it was probably just a few extra stats and Bloodshed.
If 100% Block by itself was enough, though, Irene with a similar build would be dominating too, but she lacks the most important thing that Albus has, which is the ability to fight AT delay. Not only does Albus have Wind Veil to ignore AT delay, he also has Weapon Blocking to cut off 10 AT every time he gets hit, feeding him constant extra turns as he tanks, dishing out more forced Forestallment crits from Sen no Sen. Add Second Wind later when you have the points and slots for it and he'll tank whatever gets thrown at him. I just went for general useful stuff like Combat Training and Repetitive Sword Training, plus Sword Manual is nice at some point. Can go for Bleed rather than Second Wind too.
