Croc Business hits 3 highest-HP targets for 650% damage with +200% bonus against enemies with higher HP than Leon — relevant against mech bosses. 60% Stun chance provides CC utility.

Sewer Surfing's stat block (ATK+50%, Block+30%, AB+30%) is solid for sustained damage. Sacred Scales' Bleed/Poison healing is wasted in mech where DoTs are rare. Block healing from Sharp Reflexes provides some survivability. Not a top mech pick but viable.

Tanky Mantis brawler for club smash. 4.2M HP with Block+30% and Control Resist+30% makes Leon difficult to remove. Sacred Scales completely negates Poison and Bleed strategies, making him a strong Mantis-mirror counter.

Sharp Reflexes' counter-attack on crits punishes enemy Finishers with 300% armor-ignoring damage and -40% DR debuff. Croc Business' 650% to 3 highest-HP targets pressures enemy tanks. Solid frontline anchor but lacks the carry potential of dedicated damage dealers.

Elite anti-DoT tank for PvP. Sacred Scales converts all Bleed and Poison damage into 400% healing — completely countering DoT-based compositions (Lily, Vex, Primm). Sharp Reflexes punishes crit-heavy enemies with 300% armor-ignoring counter-attacks.

Block+30% with 500% ATK heal on blocks provides exceptional self-sustain. Croc Business' HP-based targeting hits the tankiest enemies. Control Resist+30% resists CC chains. A strong anti-meta pick that shuts down DoT and crit strategies.

Exceptional durability for hard-mode content. Sacred Scales turns enemy Poison/Bleed into massive healing (400% of damage). Sharp Reflexes' block healing (500% ATK with 77K attack) provides ~385K HP per block.

Croc Business targets the 3 highest-HP enemies, naturally hitting bosses and elite minions. 60% Stun provides CC utility. 4.2M HP base with Block+30% and Control Resist+30% ensures Leon survives through multiple waves. One of the most durable Mantis hard-mode picks.

Elite Mantis sewer fighter. Sacred Scales is game-changing in sewer attrition — converting all Bleed/Poison DOTs into 400% healing makes Leon nearly unkillable against DoT-heavy sewer enemies. Block healing (500% of 77K ATK) adds another sustain layer.

Sewer Surfing's full stat block (HP+40%, ATK+50%, Block+30%, CR+30%, AB+30%) makes Leon a self-sufficient frontliner. Sharp Reflexes' counter-attacks on crits add passive DPS while the -40% DR debuff amplifies team damage. Core Mantis sewer pick alongside Lucius and Hana.

Tanky brawler for campaign progression. 4.2M HP and strong defensive passives (Block+30%, CR+30%) provide multi-wave survivability. Croc Business' HP-targeting hits the strongest enemies in each wave.

Sacred Scales' DoT healing is situational in campaign (depends on enemy compositions). Sharp Reflexes' counter-attacks add supplemental damage. Solid campaign tank but lacks the AoE damage output of dedicated campaign carries like Lily. Better as a survivability anchor than a primary damage dealer.
