+### SPELL_BEGIN_CAST_EVENT
+Event you can register in game to get updates when the clien is about to attempt casting a spell. At this stage the spell is ready and has a valid target, but the spell cast might still be rejected based on line of sight or other factors.
+
+The event is `SPELL_BEGIN_CAST_EVENT` and has 2 parameters:
+1.  int spellId
+2.  string targetGuid - guid string like "0xF5300000000000A5"
+
+targetGuid will be “0x0000000000000000” if the spell requires no target
+
+Example (uses ace RegisterEvent):
+```
+Cursive:RegisterEvent("SPELL_BEING_CAST_EVENT", function(spellId, targetGuid)
+	print(spellId)
+	print(targetGuid)
+end);
+```
+
 ### SPELL_DAMAGE_EVENT_SELF and SPELL_DAMAGE_EVENT_OTHER
 New events you can register in game to get updates whenever spell damage occurs. SPELL_DAMAGE_EVENT_SELF will only trigger for damage you deal, while SPELL_DAMAGE_EVENT_OTHER will only trigger for damage dealt by others.
