Here, my fix for Warrior Maiden Call of Valhalla

open file unit_special_attacks.lua in ses.kfs, and search "Valhalla". Then replace this

function special_valhalla_call_calccells()
  local level = Attack.get_custom_param("level")
  if level == nil or level == "" then
    level = 4
  else
    level = tonumber(level)
  end

  local ccnt = Attack.cell_count()
  for i = 0, ccnt-1 do
    local cell = Attack.cell_get(i)
    if Attack.act_ally(cell) then
      if (Attack.act_level(cell) <= level) then
        if Attack.act_applicable(cell) then
          if (Attack.cell_dist(0, cell) >= 1) then
            local size_last2 = Attack.val_restore(cell, "size_last2")
            if size_last2 == nil or size_last2 == "" then
              size_last2 = Attack.act_initsize(cell)
            else
              size_last2 = tonumber(size_last2)
            end
            if ( size_last2 > Attack.act_size(cell) ) then
              Attack.marktarget(cell)
            end
          end
        end
      end
    end
  end

  return true
end

function special_valhalla_call_attack()
  local target = Attack.get_target()
  if target ~= nil then
    Attack.aseq_rotate(0, target, "special")
    local dmgts = Attack.aseq_time(0, "x")

    local power, power_max = text_range_dec(Attack.get_custom_param("count"))
    power = power*Attack.act_size(0)
    local act = Attack.get_caa(target)
    local count0 = Attack.val_restore(act, "size_last2")
    if count0 == nil or count0 == "" then
      count0 = Attack.act_initsize(act)
    else
      count0 = tonumber(count0)
    end
    local count1 = Attack.act_size(act)
    local rephits = math.min( power, (count0 - count1) )*Attack.act_get_par(act, "health")
    Attack.cell_resurrect(act, rephits)
    Attack.atom_spawn(act, dmgts, "magic_wing", Attack.angleto(act))

    local count2 = Attack.act_size(target)
    Attack.log_label("respawn_")
    Attack.act_damage_addlog(target, "res_")
    Attack.log_special(count2-count1)
  end

  return true
end

or you can use my edited file Call of Valhalla ability will work

ps: sorry for my bad english !
