Reroll weapon question help

I’m trying to reroll a blue magic weapon into a cruel prefix, does it matter what gems to use? I’ve tried 3 chips, 3 flawless 3 perfect, they all seem to work but some give sockets and a reroll. Does it matter which gems to use?

3 perfects to reroll a magic with the same item level
the others are socketing recipes with fixed (low) item level
so start with a high item level ad 3 perfects

Each combination of gems is a different recipe, and create a new magic weapon with a different ilvl

3 chipped -

Recipe: Socketed Magic Weapon ilvl 25 - ilvl 25 (and will add socket)
3 flawless -

Recipe: Socketed Magic Weapon ilvl 30 - ilvl 30 (and will add socket)
3 perfect -

Recipe: Random Magic Item of Same Type - ilvl = original ilvl of the item. Generally the level of the monster that dropped it (or your level -5 to +4 if you gamble) (and will lose any previous socket)

Cruel alvl is 51 for magic weapons - https://classic.battle.net/diablo2exp/i ... /pre.shtml)

So only the last Recipe can create weapons with Cruel affix, and you need a a weapon with enough ilvl (probably any weapon that dropped on Hell or that you gamble with a high level character will work)

I started with a

Colossus Blade, trying to get cruel

Colossus Blade of quickness.
So the best chance is to use 3

Perfect Gems? When I use chips and flawless it still rerolls it to a new magic variant of the colossus.

best no... the only one that may roll Cruel is the 3

Perfect Gems Recipe

But it is not recommended to spend your

Perfect Gems re-rolling a weapon...
If you trade, you can easily trade some

Perfect Gems for a unique/set/runeword sword that will be way better than a cruel magic weapon...
Or if you don't trade, spend your time farm runes on

The Countess.

people normally use the

Recipe: Random Magic Item of Same Type only on charms and some specific class items.
