Exploring

World of Warcraft has a game mechanism that grants you XP for exploring new areas (sometimes called regions, sub-regions, zones, or sub-zones).

Gained XP depends on area level from AreaTable.dbc If the player is within 5 levels of the area level, then the player gains Base XP.

Base XP has no known formula yet, but this table has been gathered from gameplay:

Area Lvl	Base XP		Area Lvl	Base XP		Area Lvl	Base XP
0	0		24	195		48	440
1	5		25	200		49	455
2	15		26	210		50	470
3	25		27	220		51	490
4	35		28	230		52	510
5	45		29	240		53	530
6	55		30	245		54	540
7	65		31	250		55	560
8	70		32	255		56	580
9	80		33	265		57	600
10	85		34	270		58	620
11	90		35	275		59	640
12	90		36	280		60	660
13	90		37	285		61	970
14	100		38	285		62	1000
15	105		39	300		63	1050
16	115		40	315		64	1080
17	125		41	330		65	1100
18	135		42	345		66	1130
19	145		43	360		67	1160
20	155		44	375		68	1200
21	165		45	390		69	1230
22	175		46	405		70	1250
23	185		47	420		-	-

From this table you can write function GetBaseXP(area_level) which returns Base XP

If the player is more than 5 levels below the area level then the player gains less XP:

 percent = 100-(((player_level-area_level)-5)*5)
 if percent < 0 percent = 0
 if percent > 100 percent = 100
 XP = (GetBaseXP(area_level) * percent) / 100

If the player is more 5 levels above the area level then the player also gains less XP:

 XP = GetBaseXP(player_level+5)
