well i noticed that too maybe they googled it or somth?:D

If you hover your cursor over it it tells you. It basically boosts your stats.

You invest in thouse Group(aka Guild) skills to boost certain Stats in your Team. One can boost your HP, the next one Def and so on.

See it as extra Stats bonuses you can get in the Game to get stronger ^^.

gain

it boosts your hp lol

hi im a bit confused on the group skill description in the bottom. it says "when the level of skills is higher than that of your group, they will become ineffective" does this mean if my group level is 2, i shouldn't level up group skills (attack/defense gains) above 2?
would leveling my attack gain skill to 10 not work since my group level is only 2?

Pay closer attention to the pic you post and reread what it says.

i think im *,or too faded lol ive reread it and i still dont understand :L so is it safe to max out the group skills at group level 2?

Of course you should max it as it gives you much Power

Its safe until you wont leave and join a lower lvl group. If the skills max lvl wont match its gets deactivated.

ohhh ok thanks for clearing this up!

Yes it is safe. and it says " learned group skills will be ineffective when you LEAVE not level XD"
So the bonus will always work unless you left your guild they will be disabled until you join another guild. So don't worry It's safe to max them out any time.

Life gained - increases the overall life point of your team

Similar to strengthening your equipment, the first five skills refer to your basic attributes that you can see on your main character interface. Pretty self explanatory, leveling up attack gains will increase your attack etc.

The last five you can see in the additional attributes section of the details. *ion is to increase the chance of causing higher damage to your opponent in the range of damage that you can make. Damage reduction is the counter of this, which reduces the damage caused by your opponent. Life recovery is just the amount of life point restored to your team after each round.

I would suggest leveling up the first five first, as they have a greater effect on your power. It has been experimentally tested by people from the Chinese version that the two *ions make very little difference in your battle, so unless your have maxed all the other ones and still got a lot of contributions left, they are not recommended.

how to join a group thank you in advance

You apply to a group through the group interface. Also, please do not bump up old post in the future. Thank you! :D
