## Notes

* **Lua error in Module:ImageLink at line 174: attempt to call field 'arguments' (a nil value).** will trigger on any source of damage which triggers spell effects, regardless of the type of damage.
* Each spell cast will generate 10 charge.
	+ Toggled abilities do not count as spell casts, such as **Lua error in Module:ImageLink at line 148: attempt to call field 'arguments' (a nil value).** **Lua error in Module:ImageLink at line 110: attempt to call field 'arguments' (a nil value).**, **Lua error in Module:ImageLink at line 148: attempt to call field 'arguments' (a nil value).** **Lua error in Module:ImageLink at line 110: attempt to call field 'arguments' (a nil value).**, **Lua error in Module:ImageLink at line 148: attempt to call field 'arguments' (a nil value).** **Lua error in Module:ImageLink at line 110: attempt to call field 'arguments' (a nil value).** / **Lua error in Module:ImageLink at line 110: attempt to call field 'arguments' (a nil value).**, **Lua error in Module:ImageLink at line 148: attempt to call field 'arguments' (a nil value).** **Lua error in Module:ImageLink at line 110: attempt to call field 'arguments' (a nil value).** and **Lua error in Module:ImageLink at line 148: attempt to call field 'arguments' (a nil value).** **Lua error in Module:ImageLink at line 110: attempt to call field 'arguments' (a nil value).**.

* **Luden's Echo** applies spell effects as  area damage.
* Note that **Luden's Echo** does not affect the classification of the triggering ability - an ability that applies  spell damage will apply spell effects from that damage classification, and not **Luden's Echo's**.
* **Luden's Echo** will not apply champion-specific spell effects, such as **Lua error in Module:ImageLink at line 110: attempt to call field 'arguments' (a nil value).**, nor duplicate the effects of a champion ability (e.g. **Lua error in Module:ImageLink at line 110: attempt to call field 'arguments' (a nil value).** will not blind all enemies hit and **Lua error in Module:ImageLink at line 110: attempt to call field 'arguments' (a nil value).** will not generate <span style="color:**Script error: The function "keyword" does not exist.**;">ability power for every enemy killed or enemy champion hit).
* For large area of effect abilities, **Luden's Echo** will pick a main target based on the pick order.
