Start with what you are trying to change. Each card separates the part that moves, the part that stays, and the risk you accept.
Move a normal base through magic and rare states while deciding when another random property is worth accepting.
Replace the modifier set on a rare item when the current result is not worth keeping.
Work on a partly useful rare item one property at a time, without pretending the affected property is guaranteed.
Keep the named modifiers but reroll their numeric values within their permitted ranges.
Use an Essence when one guaranteed property is more useful than beginning with a completely broad random roll.
Treat socket count, socket colour, and links as separate crafting questions instead of one combined roll.
Use the planner to check whether the desired modifiers fit the base and each other. It checks compatibility—not price or guaranteed success.
