Hero
Cheiromancer said:If it's a magical ability then it can be added to other magic items with virtually no restrictions. A flat "no" hardly counts as "virtually no restrictions." And once it is added to another magic item, then it would exist outside the Crystal Echoblade.
That's abuse of English. It doesn't say "you can add anything to anything." It says only that you won't be prevented from adding something. It still has to be something you can add. You cannot, for instance, add a property to a longsword that gives +4D6 RKA AP, because that's a Hero System game statistic.
I have yet to see a specific cite IN THE RULES (not really horrible examples) that states you can ignore the cost of OTHER WEAPON QUALITIES when you upgrade a weapon.
By the logic that has been presented so far, I should be able to upgrade a +1 flaming keen longsword as though it were a +1 flaming longsword, and treat the keen property as an add on cost.
The echoblade's bonus is not a SLA, not an ability score bonus, not a bonus to something else... it's a weapon quality.
