The quest is totally wrong. Try this one:
quest yourquest begin when login begin   local boss = {101, 102, 103, 104}   local escolha = math.random(1,1) -- math.random(1,1) is always 1... dou you really want this??   if escolha == 1 then    local mob = boss[number(1,table.getn(boss)]    pc.setqf("mob", mob)    pc.setqf("state", 20)    q.set_counter("eventkill:", 20)    say("kill mob"..mob_name(mob).."")   end end when kill with not npc.is_pc() begin   local mob = pc.getqf("mob")   if mob == 0 or npc.get_race() ~= mob then return end     local count = pc.getqf("state") - 1   if count <= 20 then    pc.setqf("state", count)    q.set_counter("eventkill", -count)   end   if count == 0 then    local itens =  {{27005, 200},{27002, 200},{27006, 100},{27003, 100}}    local reward = number(1,table.getn(itens))    pc.give_item2(itens[reward][1], itens[reward][2]) pc.delqf("mob") pc.delqf("state")   end end end I've just fixed the errors, but this quest is still a sh!t. Look at a hunting quest and modify to your needs.

It's unable to unpack type4 packs with general unpackers. The only way (as i know) is the "unpacker for every client".

Try notice_in_map("my notice", 1)
 
Second argument is 0 or 1 (false/true) means BIG_NOTICE (maybe)

Are your map2 and arena on the same gamecore? (because they must be)

Try a debug version:
when login begin local mapidx = pc.get_map_index() syschat("Map index: "..mapidx or "error") if 352 == mapidx then ...
