Eternal reinforcement
Eternal reinforcement is a members item. No shop sells Eternal reinforcement and no monster drops it, so an Ironman makes it: it takes 105 Construction and gives 499,200 Construction XP, using 65 × Eternal frame and 6 × Stone wall segment.

Ironman verdict
Where the materials come from: Eternal frame (made with 95 Construction); Stone wall segment (made with 1 Construction). Making ten takes 650 × Eternal frame and 60 × Stone wall segment and gives 4,992,000 Construction XP. Reaching level 105 Construction takes 23,611,006 XP in total; the Construction calculator counts the actions and materials to any target, and the Construction guide has the Ironman training route. Eternal reinforcement is members-only. It is untradeable, so every account, Ironman or not, gets it the same way.
