Exploring

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

Gained XP depends on area level from AreaTable.dbc If player level is not more than +5/-5 from area level, then player gains Base XP

Base XP have no known formula yet, but there is table (levels after 56 are hypothetical):

Area Lvl	Base XP		Area Lvl	Base XP		Area Lvl	Base XP
0	0		22	175		44	375
1	5		23	185		45	390
2	15		24	195		46	405
3	25		25	200		47	420
4	35		26	210		48	440
5	45		27	220		49	455
6	55		28	230		50	470
7	65		29	240		51	490
8	70		30	245		52	510
9	80		31	250		53	530
10	85		32	255		54	540
11	90		33	265		55	560
12	90		34	270		56	580
13	90		35	275		57	600
14	100		36	280		58	620
15	105		37	285		59	640
16	115		38	285		60	660
17	125		39	300		61	680
18	135		40	315		62	700
19	145		41	330		63	720
20	155		42	345		64	740
21	165		43	360		65	760

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

If player level is less than area level on 5 then 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 player level is more than area level on 5 then player also gains less XP.

 XP = GetBaseXP(player_level+5)
