Viking Chief is a level 3 boss in Evony TKR.
Viking Chief has a power of 262,700,000 and is considered a extremely hard event boss.
The Viking Chief is final stage three of three viking bosses. The requirements to challenge the Chief is that at least 10 alliance members must complete the level 30 viking trial under hard difficulty. You will also need to have defeated the Viking Icebreaker and the Viking Berserker previously. Only R4 and R5 of an alliance can challenge the Chief and other viking bosses.
You can only challenge and defeat each viking boss once.
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, 1,600,000 T14 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 Chief 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 Chief gives 6,000 monarch experience when killed. It also grants 600 alliance honor, 600 alliance points and 500 prestige. Viking Chief also gives 11,460 general experience when a general tags along in the fight or runs the rally.
