To upgrade Gunnar Nielson to SL.2 in Pirates of the Caribbean : ToW, stockpile a large reserve of Rare Tactician Letters—targeting around 900 or more—to open in bulk. Large-scale pull sessions generate the volume of tactician shards, duplicate fragments, and gift currencies required to cross high-tier promotion thresholds without stalling your progression.
Why Stockpile Rare Tactician Letters
Opening Rare Tactician Letters incrementally scatters shards across the entire rare roster. Because the pull pool contains multiple tacticians, small batches leave your officers stranded between star and special-level (SL) milestones without enough duplicate pieces to trigger rank upgrades.
Accumulating approximately 900 letters guarantees a steady influx of targeted pieces alongside general recruitment resources. This concentrated yield allows you to funnel materials directly into Gunnar Nielson, securing the SL.2 threshold in one session rather than waiting on sporadic individual pulls.
| Resource Category | Session Yield Role | Immediate Account Application |
|---|---|---|
| Gunnar Nielson Shards | Direct upgrade material | Fills the specific shard requirement for the SL.2 promotion |
| Off-Target Tactician Gifts | Duplicate conversion currency | Covers remaining gift deficits if direct piece counts fall short |
| Tactician Invitations | Supplementary recruitment | Unlocks additional tacticians and provides secondary upgrade currency |
| Account Power | Fleet attribute scaling | Lifts total combat rating toward multi-billion power milestones |
Steps to Upgrade Gunnar Nielson to SL.2
Follow this sequence once you assemble your stockpile:
- Verify Base Requirements: Open your tactician menu and confirm Gunnar Nielson has reached his current level cap. A tactician cannot execute an SL breakthrough if prerequisite base levels remain unmet.
- Execute Bulk Letter Openings: Open your accumulated Rare Tactician Letters in high-volume batches. Collect all direct Gunnar Nielson shards, general tactician gifts, and invitations.
- Convert Collateral Resources: If your direct Gunnar shards fall slightly short of the SL.2 threshold, use the generic tactician gifts and duplicate conversion currencies acquired during the session to bridge the remaining deficit.
- Trigger the SL.2 Breakthrough: Enter Gunnar Nielson's promotion screen and commit the required shards and upgrade gifts to finalize the SL.2 advancement.
- Assign to the Flagship Fleet: Assign Gunnar Nielson to your primary combat fleet or rally formation to apply his upgraded skill ceilings, defensive shielding, and damage buffs to active sea battles.
