Power Combos (Biotic & Tech Bursts)





Biotic Combos (Warp + Throw or Pull + Warp)



• Warp + Throw: Detonation deals 400+ damage in an area. Trigger when Warp hits an lifted enemy.


• Pull + Warp: Similar damage; Pull sets up, Warp detonates.

• Incinerate + Overload: Fire explosion; deals 300 damage to armored enemies, 150 to others.


• Cryo Blast + Incinerate: Shatter combo; deals 200 damage to frozen enemies. Use on frozen targets.


• Use: Incinerate first then Overload; or freeze then incinerate.




Power Synergy Recommendations



• Shepard (Adept) + Jack: Singularity + Shockwave = mass biotic detonations.


• Shepard (Engineer) + Tali: Combat Drone + Energy Drain = constant shield drain and distraction.


• Shepard (Infiltrator) + Garrus: Tactical Cloak + Overload + Proximity Mine = high burst on bosses.


• General rule: Use squadmates with complementary powers (e.g., one for shields, one for armor).

Upgrading Skills (Research & Experience)



• Skills improve by spending skill points (earned per level up: max level 30 in base game, 60 in Legendary Edition). Each skill has 4 ranks; rank 4 offers two evolutions (e.g., damage vs. radius).


• Evolutions unlocked at rank 4 and 7 (if using Legendary Edition’s increased level cap).


• Some skills require Loyalty Missions to unlock (e.g., Reave for Samara, Assassin Cloak for Zaeed).


• All skills have a base cooldown; upgrades can reduce cooldown.




Recommended Builds



• Shepard Soldier: Max Concussive Shot (damage+radius), Adrenaline Rush (duration+damage), then weapon passives. Very simple, high damage.


• Shepard Adept: Max Singularity (radius+damage first), Warp (damage+detonation), then Throw (force+cooldown). Use combos constantly.


• Shepard Vanguard: Max Charge (shield restore+damage), Pull (duration), Warp (damage). Charge, Pull, shoot, repeat.


• Shepard Infiltrator: Max Tactical Cloak (damage+speed), Incinerate (damage+armor piercing), then Overload (chain). Sniper focus.


• Shepard Engineer: Max Combat Drone (stun+damage), Overload (chain), Incinerate (damage). Drone draws aggro while powers strip defenses.


• Shepard Sentinel: Max Tech Armor (damage reduction+shield), Overload (chain), Warp (damage). Survivalist.

Conclusion

Mastering all 12 squadmates and Shepard’s class skills is key to surviving the Suicide Mission. Focus on building synergies: biotic pairs (Jack+Samara), tech pairs (Mordin+Tali), or hybrid. Always upgrade at least the essential powers for your playstyle. In Legendary Edition, you have more skill points; invest in evolutions that match your combat approach. Remember: powers are only as good as your squad coordination.
