Circlet of the Iron Solari's base stats were 102.27% gold efficient.
Circlet of the Iron Solari became gold efficient whenever the active provides a minimum of 169 health as a shield. (Not factoring in the percent bonus health bonus for the shield, this can be achieved with 2 nearby allies at level 3 or by the user alone at level 8).
The raw stats gained from upgrading Locket of the Iron Solari into Circlet of the Iron Solari were worth 570 (15 magic resistance and 15 armor).
This item was inspired by the Iron Solari Conclave, a fan-made forum group that was named after Leona and is supported by Michael 'IronStylus' Maurino. Numerous other groups, led by various Riot staff members, were also formed and "warred" with the Iron Solari, but the Iron Solari were arguably the most successful.
A reworked version of this item once existed on the PBE for testing to be potentially shipped to V8.6. The active was changed to deploy a small field on the target area that granted damage reduction to all allied champions within. This was later scrapped and reverted.
Unique Active: Grants a decaying shield to nearby allied champions and yourself for up to 2.5 seconds, absorbing up to 60 − 434 (based on highest level between target and caster)(+ 2% − 36% (based on level) of caster's bonus health) damage. Shielded targets are Eclipsed for 8 seconds (90 second cooldown; 650 radius).
