Yes, a creature can potentially be attacked multiple times by Tsunami. At most, this could hit the same creature 4 times plus end with a bash attack against the Arena walls.

Note, that you get to choose the direction of the Tsunami but NOT the direction of the Push. Pushes are always directly away from the source of the push (in this case probably the Mage) unless otherwise stated. This can make lining up such devastating Tsunami's tricky to do, and really the only way to do the 4 attacks + bash that I previously mentioned is if your Mage was in the starting zone that you targeted, so you'd take some damage as well.

if there are two(or three) optional directions for the push effect, the caster of the spell decides where opponent is pushed?

i have only one buddy against i'm playing but he is competitive we change our mages , prepare them in secret so no one knows which mage will have opponent. He has his favourite Priestess, but not playing it all the time. he also don't have DvN expansion unfortunately.

thanks @Gogolski

i have two other ideas:
first one is connected with Seedling Pods - a Creature, probably Tree with all that Uproot things, Regenerate etc. the cool things would be, when it gets hit it's reproducing (whenever this creature takes damage it can cast Seedling Pod from your hand or spellbook without any cost). Of course it can be limited to only once on a turn and to cast Seedling Pods only in this creature's area, but it's someting for testers

second idea is a vine type Creature let's name it Tentacle Vine (it should be level 1, so it's cheep and player could take 6 into spellbook) with poor stats on it's own, for example: 1 die attack, armor 0, life 5, uproot 1, regen 1  but with special skill that it gets +1 melee  for each friendly Tentacle Vine creature in different zones in Arena. Bonus counts only for connected zones.
Explanation: This creature is weak, but gets stronger when it gets bigger and takes more and more space on Arena. To achieve that you need to have as many Tentacle Vine creatures in contiguous zones, even they can be separated by walls, because vines can go in the ground

are you guys still doing movies not from OCTGN but normal, traditional boardgame?

i can imagine Paladin having access to some kind of auras which affects all friendly creatures in hi zone (it can give them armor, melee, piercing, regeneration, tough etc). it can be done by enchantments, his skills or equipment...

i see it that way: most of Arena fans will buy it to at least get the cards(so it's good for Arcane Wonders). Once it is bought it can be presented to people that don't know Mage Wars or it was to big to start for them (chance to get more people in to Academy and/or Arena).  While it is shorter and portable version then Arena it will fill up some space that Arena rather can't do, so after all it's good move. If i only have occasion to play i will open Domination or Arena mode, but in some cases Academy will be better/only option

I think I found a missingo by accident

Wow, nice finding. He looks so cool! Maybe he will appear one day in official game with this stats or modified.

Hi, thanks for video, nice editing (reset part was funny:) )

i think there was also one more rules mistake when battle fury buffed up Warlord was making second attack. he used 4 + 4 dice and i think it should be 4 + 3.  if he made less damage, Grunt Goblin who had 1life left wouldn't be so sure to make an attack on guarding Ssalak.

I can't wait when Domination will be available in Poland. I want to try this mode, looks fun and better for free for all games.
