I'll start from the basics and mean no disrespect as I do not know how much you know based on reading or if you've tried out the game already.
There are 4 common places to fight monsters.
1st place: mission maps. Also known as f1/f2/f5.
This is the one you will be most familiar with when you start playing the game. It is called mission maps. There can be 1,2,or 3 maps of monsters that you have to exterminate before moving on to the boss room, which would be the 4th room(if you took 3 maps) F1 will always match your level unless you are above the level range of the respective mission map.
F2 is basically F1, but it will be 2 levels above you at all times, unless you out level the range of the mission map.
F5 is main quest scenarios where you need to do a quest to unlock it. It will always have 2 maps and then a boss map after.
2nd Place: F6
F6 is unlocked when finishing F5 with the hero quests that lead up to it. This mode has a crystal in the middle that you must protect. Monsters spawn either from the left or right side and you have to fend them off by killing them. 10 Rounds with a certain amount of "waves" every round.
3rd Place: F7
This is a tower defense game, you kill some monsters to get points, then build towers that will kill the monsters because every round they become much stronger and you won't be able to just kill it normally anymore. Unlocked only at 40 when you do the quests for it.
4th Place: Dungeons
Every mmorpg needs a dungeon. This is exactly what it sounds like. Kill monsters get to the boss room. Slay the boss and get a chance to get good equipment.
Now you can all do these by yourself as a invoker. You can do all of these with any class in fact(except the end game dungeon but that is far away from where we are starting at). If you want to party that's your choice and support the players killing the monsters. This class is capable of dealing more damage than 70% of the other classes we have, so if you ever feel like not sitting back afk and healing whenever, you can kill those monsters faster than the ones you are with .
If you have more specific questions on skills or something else, I'll answer them. The points distributed is totally random, it isn't meant for anyone to follow.
People will most likely shut you off if you do not take the awakening, but your friends will either try to convince you to take them because they are useful or just ignore that and just accept you for what you do and choose.
