If you decide to play a raid, you'll notice that there are many choices to pick from. There are three major tiers: D C, and B. Each level gives more bloodstones than its predecessor (with B providing the highest amount). If you are doing them in Lost Ark Gold an organization, you should choose the top tier to get the highest rewards in terms of bloodstones from symael. If you are doing them on your own it is advised to choose the D tier as the other tiers are very difficult (almost difficult) to do solo. Remember that all tiers offer an equal amount of guild contributions, which is 150.

Additionally there are 3 subcategories that are based on the maximum number of participants: 10 20 and 50. Each one of them offers identical rewards with respect to bloodstones as well as contributions, so the only reason to choose the 50-person category is if you've got more than 20 participants. If you're a solo player there's no reason to pick any other option than the 1-10 person group (easier than the other categories and with the same rewards).

In the end the situation, if you're playing solo choose D tier and 1-10 players raid the same tier, which is Rudric (some players also suggest choosing Rudric instead). Salt Giant instead of Rudric because, despite having higher HP, it's easier to avoid). If you're part of a guild or group, select B tier and which raid is suitable for all players.

Guild Raid Match Challenge Mode

Instead of choosing Enter Base initially players can choose Challenge. It is a challenge for competition in which players must clear the boss as quickly as they can. They will compete against other guilds that have fought the same boss during the same week. The best guilds earn additional rewards in the form of bloodstones from Symael and guild XP. In the challenge mode, guilds must bring the highest number of players to guarantee quicker clearing times, and Buy Lost Ark Gold also use Dark Grenades to boost damage. Remember that getting the top three spots to receive the gold rewards is extremely difficult due to the fact that the competition is intense.
