Life Preserver

Aquatic Heal Shield
Efficiency Score
5
Best Positioning (Quick Answer)
Placement: global effect (no slot requirement).
Trigger: global • Risk: None • Check: No
Life Preserver
Key Takeaways
  • ● Filler — strongest when purchased with a plan, not as a blind buy.
  • ● Low friction: only 2 slot(s), easy to slot in during pivots.
  • ● Low placement risk: trigger is global, so disruption is less punishing.
ⓘ Data & Methodology (How scores are calculated) Season 10

Efficiency: Efficiency Score is a normalized "space ROI" metric: (estimated effect value ÷ size slots). It is NOT raw DPS.

ROI: ROI estimates assume standard round pacing and compare this item against same-tier peers by cost and slot usage.

Percentile: Percentiles are computed within the same category/tier bucket (e.g., Tech items at similar cost).

Meta Strategic Position

The Life Preserver is best classified as Filler. At 4g and 2 slot(s), it’s a placement-safe (global) item where timing matters.

Low-to-mid cost means it can be used as a tempo stabilizer if it fits your board plan. Large footprint means you must plan around board compression and sequencing.

Quick Conclusions

Verdict: Situational — based on efficiency 5 and cost 4g.
Trigger: global — placement-safe (won’t usually break).
Best synergy: Ambergris (score 2 • shared tags: Aquatic, Heal).


### Efficiency & ROI Analysis
Your efficiency score (5) is a *space ROI* signal, not raw DPS. This usually means it needs support pieces and correct timing to justify the slots. If you’re behind on board stability, delay the purchase until you can immediately benefit from it.

Opportunity Cost

Because it is Medium, you’re paying in board space. Plan your next 2–3 rounds so you don’t choke your sequencing or block key triggers.

Efficiency: 5 Role: Filler Slots: 2

Investment ROI

Estimated break-even: ~1 rounds
ⓘ Method

This is a heuristic estimate (not raw DPS). If you want it to matter, buy early enough to get multiple trigger windows before the board locks.

Timing hint: strongest when purchased before ~round 8 (due to 2 slot footprint).
Cost: 4g Est. Rounds: ~1 Model: cost ÷ (eff×2)

Positioning Guide

Trigger: global • Risk: None • Check: No

Optimal Layout

No positioning requirement (global effect).
Life Preserver

Placement does not change whether the effect triggers.

Why Placement Matters

Placement errors won’t nullify Life Preserver. Focus on board space and upgrade timing instead of slot order.

Strategic Q&A

Is Life Preserver worth buying early game?

"With a cost of 4g, this is typically a priority pickup. In early rounds, focus on board stability before committing to this Medium item."

Does positioning matter for Life Preserver?

"No — this is a global item. Placement won’t affect whether it triggers. Optimize for slot efficiency and keep your grid open for higher-impact pieces."
