In my Land of M’kal game I am using custom legacy items for my players. Rules on those are here.
1. A Legacy item may be awarded to you from your family line.
2. You must have a story to go with your legacy item to suggest why it has sentimental value for you.
3. Your legacy item does not level with you. It levels when the GM says it does. This will often be tied to quests and deeds.
4. The table below will tell you the maximum value of your item at each level. This is the maximum completed value at that level, not cumulative.
5. Once a magic is added to the item it cannot be removed or replaced. That +1 jump you put on will always be there unless you up it to +2. You can’t swap it for +1 dance, or remove it at all.
6. Use standard enchanting/crafting rules for these. Ignore epic crafting rules completely.
Examples of Legacy items that have been used so far;
Morticia’s Hand Crossbow:
The weapon came engraved with a poem that spoke of how teaching people of pain is also an act of love.
Every sneak attack the weapon gained 10xp per point of damage done. It levels up at the same rate as a PC does, and as it levels up it’s MAX value according to the table above.
