Viking Berserker is a level 2 boss in Evony TKR.
Viking Berserker has a power of 134,100,000 and is considered a extremely hard event boss.
The Viking Berserker is stage two of three viking bosses. The requirements to challenge the Berserker is that at least 10 alliance members must complete the level 20 viking trial under normal or higher difficulty. You will also need to have defeated the Viking Icebreaker previously. Only R4 and R5 of an alliance can challenge the Berserker and other viking bosses.
You can only challenge and defeat each viking boss once. After successfully defeating the viking boss, you can move on to the next difficulty, or Viking Chief.
As with all bosses, mounted troops led by a strong mounted general with mounted gear, skills and refines is your best bet to effectively take them down. Investing in mounted research and technology is also very important.
For mounted troops, 1,700,000 T13 with a general of your highest level wearing the best mounted gear you have should be sufficient to kill, although wounded will depend on how high your tech, research and debuffs are into mounted buffs.
Being an end game boss, Viking Berserker is extremely difficult. Alliances will rally this boss as a team, with multiple higher level players contributing their mounted marches.
Most bosses when killed will consistently grant monarch experience, general experience, prestige, alliance honor and alliance points. Viking Berserker gives 5,000 monarch experience when killed. It also grants 500 alliance honor, 500 alliance points and 450 prestige. Viking Berserker also gives 9,550 general experience when a general tags along in the fight or runs the rally.
