Tsunami

Tsunami is a Pyratite-tier liquid turret that projects a continuous stream of liquid as its ammunition. It first appeared in Version 6.0 (Build 108) and is built quickly (build time reduced to about 13.16 seconds in later patches). The turret fires at a sustained rate and consumes large amounts of liquid, so it is commonly paired with Liquid Tanks and pump infrastructure to keep it supplied. Water rounds automatically extinguish fire on hit.

Tsunami can use four liquid ammo types with distinct effects and numbers:

• Water: 0.2 damage, 1.7 knockback, applies Wet for ~4 seconds; automatically extinguishes fires on targets and increases knockback. Water is easy to source directly from pumps and pairs well with Surge Alloy ammunition on other turrets.
• Slag: 4.75 damage, 1.3 knockback, applies Melting for ~4 seconds. Slag deals the highest damage of the four and excels at burning large groups, but is more resource-intensive because it is primarily produced from Melters.
• Cryofluid: 0.2 damage, 1.3 knockback, applies Freezing for ~4 seconds. Cryofluid strongly slows enemies and increases incoming damage; it synergizes with Blast Compound ammunition because the "blasted" status adds significant armor‑piercing damage per hit.
• Oil: 0.2 damage, 1.3 knockback, applies Tarred for ~4 seconds. Oil slows targets and can amplify damage of other Pyratite-ammo turrets, but oil production and safe storage are more difficult. Stored oil in tanks is hazardous because tank destruction causes a large explosion and widespread fires.

Practical notes and strategy:

• Tsunami consumes liquids quickly; placing a full Liquid Tank adjacent to the turret supplies continuous firing for roughly 25 seconds, so co-locate tanks or run dedicated piping to avoid downtime.
• Slag is the primary offensive option: at the common fire rate of 40 shots per second (reduced from 60 in a later update), Slag yields about 4.75 × 40 = 190 DPS before accounting for melting effects. Non-Slag liquids deal much lower direct damage (0.2 × 40 = 8 DPS), so their value is usually in utility (knockback, slow, status synergies) rather than raw damage.
• Use Water when you need cheap, continuous supply and extra knockback to interrupt swarms or specific units (for example, insectoid targets). Water also helps boost Surge Alloy turret damage through its interactions.
• Use Cryofluid to cripple high-value targets and amplify follow-up damage; pair it with turrets that benefit from the blasted/freezing synergy to maximize damage per hit.
• Use Oil to slow and debuff foes and to improve Pyratite-ammo turret performance, but avoid storing large amounts of oil without protection because destroying oil tanks can cause catastrophic explosions.
• Tsunami’s longer range makes it less vulnerable to being outranged than many close-range defenses, but some units and turrets (notably Minke and Fortress) can still outrange it. Tactics used against other continuous-stream turrets like Wave largely apply to Tsunami as well.
• Because of the turret’s liquid dependency and ammo-specific roles, mixed defenses that combine Tsunami with conventional projectile turrets and supported storage/piping provide the best balance between area denial, raw burning damage, and utility debuffs.
