help, how to Enchant wand, like convoking wand enchant 30% increase minion damage?

The implicit modifier "Minions deal (26–30)% increased Damage" is exclusive to the Convoking Wand base type. This means that other wand types cannot inherently possess this implicit modifier.

You can add explicit modifiers though. Here's some ways to do that:

1. Crafting Bench (Hideout)
Unlock crafting recipes through delves, Betrayal, and other content.
Use "Minions deal increased Damage" and "Trigger socketed spell" as crafted mods.

2. Essences
Essence of Fear (especially Deafening) guarantees minion-related prefixes:
E.g., “Minions deal X% increased damage”

3. Fossil Crafting
Bound Fossils (minion modifiers)

Combine with Dense (energy shield) or Shuddering (speed) for more focused results.

Use in a 4-socket resonator for better control.

4. Harvest Crafting
Look for:

“Reforge a rare item with minion modifiers”
“Add a minion modifier”

These give the best chance for multiple minion mods.

5. Bench-Craft “+1 to minion gems”
Must be unlocked via unveiling items from Jun missions (Syndicate).
Often used after getting another strong prefix.
