Im gonna leave this here just so ppl see how was on RO:



As you can see the first 2 skills you can level up is the guild aproval (needed to enter the War of Emperium) and the guild extension and the guild extension gives 6 slots for new people each level. The guardian research make Guardian pop on your castle when you are defending and the Urgent Call one is an active skill that can be use by the guild master to teleport every guild member to his location.

Well all this skills have the main purpose to use it on the War of Emperium but outside it can be used and will help a lot.

SE should add something like WoE, a big scale PvP where linkshells fights each others for something.
