I can't seem to find good ones for other styles !

Anyway, here it is:

Giving Your Hero's Weapon Durability

Trigger 1:
Start: ON
Loop: YES
Objective: NO
Cond.
Kill ratio = # of kills (discretionairy)
Effect:
Change Object Attack (set the area)
65535 (-1 from attack, or the weapon slowly losing it's sharpness or durability)
Effect:
Create Object: [unit] :: [area] (it's another player, not player 1)
Create Object: (in another area)

Trigger 2:
Start: ON
Loop: YES
Objective: NO
Cond.
Object selected:
(ex.)"Blacksmith"
Effect:

"Need a reparin'? It'll cost ya..."

Triggers 3-(number of attack power +3)
Cond.
Timer 10
Cond. Variable:
Objects in area (# of times object has lost durability)
Effect:

Effect:

Cond.

Cond.
Objects in area
[unit] :: [area] (# of units = number of attack pts to increase)
Effect:
Display Instructions:
Blacksmith: "Aright...done."
Effect:
Change Ownership
(those units that were created per kill ratio)
Effect:
kill objects
(those units)
Effect: activate Trig "Help"
Effect: activate next trigger

trig "Help"
kil ratio = #
effect: create object player1 :: area
effect: kill object :: area

Trigger Help2
Kill ratio = 0
deactivate trig "Help"

Trigger (next)
Start: OFF
Loop : ON
OBJ : NO
Cond.
Objects in area:
Quantity = # of those units that were created and never belonged to player 1 in Trig. 1
Effect:
Change Object Attack:
# of those units
(ex.) 65538 (+2)
Effect:
Deactivate Trigger
Self.

*Note: You can modify this trigger trick successively by letting different area affect your weapon differently.

Example:
One area is left, the previous area's triggers are deactivated.
The new area requires a lesser kill ratio to decrease durability (thus making the enemies seem more tough).

Enjoy designing!

As I always do, and always will.
Hopefully, I'll find some more stuff for you people to incorporate into other types of scenarios...
