1. Never use Leggos as chicken....not because any leggo is nice to see, but because they occasionally get buffed to God tier. Candraphon, Visix, Belanor (incoming) etc.

2. I don't have experience with him, but all AOE attacks, Decrease Speed on A1, and unresistable buff strip sound like good abilities to me. 

My first leggos were Warchief and Nobel...still in the vault, waiting for a buff. 

HellHades about Suzerain Katonn:

Suzerain Katonn is a Spirit affinity legendary from the Undead Hordes
faction. He is an Arena specialist often seen in the high end Arena due
to his unique ability on his A3 that removes all enemy buffs requiring
zero accuracy! He can remove large shields from all enemies and then
nuke some damage before your team explodes the enemies. This is
particularly strong against high shield opponents such as Arena teams
with Krisk in their line ups.

Outside of Arena he has all AOE damage and can be a great Campaign farmer or a wave clearer in Dungeons.

Suzerain is certainly worth building and often undervalued in Raid. 

P.S. @Balltazer 

I would max Warchief for Hydra. 3 turns is the longest lasting provoke in the game. Taking out the buff removing head is great if you run Geomancer.

Not necessarily worth building, no. But also never turn a lego into food. Ever.

Dude has uses, but whether he is worth it for *you* is going to depend on where/how you plan on using him.

I find him to be a one-trick pony. Hydra calls for champs with many uses. I use Krisk and Husk on my Brutal team, Var Gall on my Hard team, and may start using Maulie on Normal. If I didn't have them, I probably would have built him to keep the Decay locked in.

+1 to do not feed legendaries.

If nothing else Suzerain has his place in FW21, is great against Valk.

And imagine the starter would not have used the first one as food: +10% hp for all undead legendaries.

The stuff from HH is obsolete. Nobody that I've seen uses him in "high end arena", his one big move, irresistible shield removal, is useless in 2022, since everyone uses Bolster instead of Shield.

Cool I will keep him in the vault for now and see what happens down the line 

Yeah I've also noticed that HH is often out of date, and tends to play up niche uses that other champs cover better. Needed to learn to trust my own judgement. I still look up champs online as a sanity check, to make sure I didn't miss anything.

Suze is a fragile atk based champ that doesn't hit very hard, and his kit doesn't bring enough to justify this. That's a general problem with raid. Too many atk based champs compared to how many you actually need in most content.

I can agree with the Warchief geo combo i use it often with head of wrath in really racks up damage 

Can you screenshot next time you run Warchief on Hydra? I am curious about it now. I know Geo is known for that, but I didn't know Warchief can put out that kind of damage with his passive. I know I have to revive my Seer when I come across 3 of them in DTH lol. 

yeah I will i Love when a champ does something unexpected
