A system that adds bonus experience when killing monsters.
When player log in to the game and is in the safe area, or when parti-_-'ting in killing raid monster, he/she will gain “vitality points”
Accumulating vitality points will increase the vitality system level
When players killing monsters, the vitality points will transfer into extract experience
Vitality points, vitality system level, and vitality condition can be viewed in character status window
• 活力系統最多四階段（舉例：四階段可獲得四倍 EXP 、三階段三倍 EXPs）
Vitality system can be raised up the level 4 (for example, level 4 can gain 4 times experience, level 3 gain three times)
• 活力點數消耗公式是以獲得 EXP 量為基準，不會因時間而消耗掉
Vitality points consuming formula is based on experience amount, not based on time
Sorry about my translation skill.
If reading in my own language, what I think it means is the the increasing is based on the experence that you gain from killing monsters.
if you get 100 experences from killing A monster
with viliaty points, you will gain 100 + extract experiecne
so when your vility system level is 4, you might gain 300 experience (total possible increasing) instead of 100 for killing the same monster.
This is what I understand so far. Might be wrong @@""
Staying in safe area around 8~9 hours can raised up one level for vitality system (which means if I am busy, I can put my character in the safe area and will gain vitality points and raise up my vitality system level. When I come back and start killing monster, I will gain extract experiences).
When killing raid monster, system will inform the player how much extract vitality points gained.
Killing raid monster will gain more vitality points than simply stay in the safe area. Amount of vitality points will change according to the raid boss level.
In Korea test server, it will raise about one level after killing four raid boss (however, this information is not detailed clear)
• 活力系統 Lv.0 升級至 Lv.1 ：經驗值提升 50%
Vitality system raise level 0 to level 1: experience will raised about 50%
• 活力系統 Lv.1 升級至 Lv.2 ：經驗值提升 33%
Vitality system raise from level 1 to level 2: experience will raised about 33%
• 活力系統 Lv.2 升級至 Lv.3 ：經驗值提升 25%
Vitality system raise level 2 to level 3: experience will raised about 25%
• 活力系統 Lv.3 升級至 Lv.4 ：經驗值提升 20%
Vitality system raise level 3 to level 4: experience will raised about 50%
Therefore, if your vitality system is level 4, the experience you gain from killing monsters will become about three times more then original.
